CD Bioparticles Launches Custom Latex Immunoturbidimetric Assay (LIA) Development Services to Accelerate IVD Innovation

Sep 22, 2026

CD Bioparticles launches end-to-end Custom Latex Immunoturbidimetric Assay development services for research applications.

New York, NY, United States, September 22, 2026 /MarketersMEDIA/ -- With years of experience in the pharmaceutical and life science sectors, CD Bioparticles has announced the expansion of its diagnostic capabilities with the launch of its end-to-end Custom Latex Immunoturbidimetric Assay development services. These services offer full-spectrum assay customization ranging from particle conjugation to fully optimized kit assembly, and can help researchers and diagnostic developers to streamline IVD reagent manufacturing and clinical biomarker quantification.

The immunoturbidimetry method is an analytical technique combining liquid-phase precipitation reactions with optical instruments and automated analysis. However, due to issues relating to the size and quantity of antigen-antibody complexes, the immunoturbidimetry has low sensitivity and a narrow detection range. This has led to the development of the latex immunoturbidimetric assay (LIA). This technique uses latex microparticles that are coated with specific antibodies or antigens.

When these particles encounter the target analyte in a sample, they form specific aggregates through antigen-antibody interactions. The aggregation of these particles increases the scattering intensity or absorbance of the latex suspension. This increase is quantitatively correlated with the concentration of the target analyte in the sample. Turbidity measurements are performed using a biochemical analyser, and the entire analytical process takes only a few minutes. Compared to traditional immunoturbidimetric methods, this method offers significantly higher sensitivity, with detection limits as low as ng/mL or pg/mL.

CD Bioparticles has extensive experience in assay solutions and now offers custom services to help researchers and diagnostic product developers develop latex immunoturbidimetric assays. The company's service portfolio ranges from custom conjugation to the optimization of complete immunoturbidimetric assays. The company provides custom-made, carboxyl-functionalized polystyrene microspheres that are conjugated with antigens or antibodies and come in various sizes. CD Bioparticles also offers complete kits for the quantitative detection of a wide range of biomarkers. These products feature high sensitivity, short assay times and compatibility with automated biochemical analyzers.

CD Bioparticles offers customers carboxyl-modified polystyrene microparticles in a range of sizes (from 0.07 to 0.4 μm) that are suitable for developing latex immunoturbidimetric assay reagents. CD Bioparticles' standard products feature a moderate surface carboxyl density; products with higher or lower densities are also available upon request. Additionally, CD Bioparticles can customize the conjugation of antibodies and antigens to meet specific application requirements. Through optimization, the team can ensure high conjugation efficiency while maintaining the activity of both antibodies and antigens.

CD Bioparticles also offers reagent formulation development and optimization services to help customers improve reagent stability, optimize reaction conditions and enhance detection sensitivity. The company offers performance validation services to verify key performance indicators, including linearity, sensitivity, specificity and precision, ensuring stability across different batches and under various operating conditions.

Lee vows efforts to help swiftly resume US-N. Korea dialogue

NEW YORK — South Korean President Lee Jae Myung on Tuesday reaffirmed his envisioned role as a "pacemaker" in establishing peace on the Korean Peninsula, pledging efforts to help swiftly resume dialogue between the United States and North Korea. The South Korean president made the pledge in his address to the 81st United Nations General Assembly in New York, as U.S. President Donald Trump seeks to revive his diplomacy with North Korean leader Kim Jong-un, while inter-Korean relations remain at a standstill. "I hope the long-suspended dialogue between North Korea and the U.S. can resume without delay," Lee said. "We will lay the groundwork for this (U.S.-North Korea dialogue) to develop into a dialogue between the related parties to end the war on the Korean Peninsula and transition into a peace regime." The two Koreas remain technically at war since the 1950-53 Korean War ended with an armistice, not a peace treaty. "Fortunately, President Trump's resolve has recently created a hard-won opportunity for change," Lee said, referring to Trump's repeated expressions of interest in dialogue

First Iran flights cancelled as US sanctions set to come into force

TEHRAN — Flights from Iran to the capitals of Iraq and Oman will be cancelled as of midnight, local media reported Tuesday, hours before expanded U.S. sanctions were due to come into force. The Tasnim news agency cited a civil aviation spokesman as saying that "Baghdad and Muscat airports will no longer accept Iranian flights." "Other international flights, including Istanbul, will operate as scheduled and as usual, and at present there are no problems with these flights," Tasnim reported. According to Tasnim, Iran's aviation authorities are in talks to reroute Baghdad flights to Najaf, a major destination for Iranian pilgrims. The agency ISNA said negotiations with Oman were also ongoing. In Iraq, the government has not yet announced plans to enforce the ban, but several sources, including a senior government official, told AFP that Baghdad would comply. Earlier this month the U.S. blacklisted the Iranian aviation sector and threatened sanctions against any foreign organisation working with Iran's airlines. U.S. Treasury Secretary Scott Bessent said on Monday that Iranian airlines would

What is in the US-Greenland-Denmark security deal?

The United States, Denmark and Greenland signed a security agreement on Tuesday aimed at ending months of tension over the Danish self-governing territory after U.S. President Donald Trump's repeated threats to take control of the vast Arctic island. Here are some key components of the deal, which adds to a 1951 U.S.-Danish pact on Greenland's defence, according to a text published by the Danish government. What are the military aspects of the deal? The agreement allows the United States to establish twonew military bases — one at Narsarsuaq in southern Greenland and the other at Mestersvig on the east coast — and to expand Pituffik Space Base, currently its only active base on the island. US craft including planes and vessels get flyover, landing and undersea rights in all of Greenland, including territorial waters. The agreement does not specify troop numbers or timelines. How does the pact work with NATO? The agreement expresses support for a stronger NATO presence in the Arctic, and Denmark commits to further strengthen its own security posture in the region.

UN chief says power has polarized the world and urges leaders to cooperate

UNITED NATIONS — In a no-nonsense farewell speech, U.N. Secretary-General Antonio Guterres urged global leaders Tuesday to respond to the defining challenge today: Will the world continue on its path to fragmentation or cooperate to tackle the existential threats from climate crisis, runaway artificial intelligence and intensifying inequalities? At the heart of these crises is power, Guterres told the annual high-level gathering at the U.N. General Assembly, pointing to the “irreversible” move toward a multipolar world, the “extraordinary transfer of power” from governments to a handful of private corporations and individuals, and the increasing handover of power from humans to machines with artificial intelligence. Guterres urged leaders to avoid what he called “the great fracture – the division of the world into two rival blocs with separate economic, technological and security systems.” He rebuked might-makes-right thinking, telling superpowers to recognize “that their power isn’t so super” — that “military power alone cannot security peace” and that “no

The uncomfortable truth about aquariums

The uncomfortable truth about aquariums

Young visitors watch the beluga whales at L'Oceanogràfic in Valencia, Spain. | Miguel Candela/SOPA Images/LightRocket via Getty Images This story appeared in Today, Explained, a daily newsletter that helps you understand the most compelling news and stories of the day. Subscribe here. Four beluga whales have died in a month at one of America’s top-rated aquariums — a tragic development and, arguably, a reason to revisit the ethics of zoos. (More on that in just a minute.) The latest cetacean casualty, a 26-year-old female named Osiris, died at Chicago’s Shedd Aquarium yesterday. She follows 34-year-old Beethoven, a longtime resident of the aquarium, as well as 20-year-old Rain and 23-year-old Peekachu, who died in late August and early September.    Osiris, Rain and Peekachu were all part of the Marineland diaspora: a group of four dolphins and 30 beluga whales that rescuers have worked to relocate since the 2024 closure of a scandal-plagued theme park in Niagara Falls, Canada. This summer, the animals were successfully transferred to aquariums and marine parks in the US and Spain. That was a frankly incredible undertaking involving padded shipping containers, a police-escorted convoy and a chartered plane.  But in some regards, the international flight wasn’t even the hardest part of the whales’ journeys. Some of the animals have struggled to thrive in their new environments — even when those environments are state-of-the-art, like Shedd.  In a blog post announcing Osiris’s death, the aquarium noted that its rescued whales had been under 24-hour supervision and receiving intensive, specialized care. The aquarium is still investigating the cause of death for all four whales.  Go a little deeper View Link Believe me when I tell you that it gives me no pleasure to write the following paragraphs. I really love aquariums. In fact, as a kid, I grew up visiting the now-shuttered and much-maligned Marineland.  But incidents like these back-to-back deaths should prompt us all to ask ourselves who aquariums and zoos are actually for. And the answer, I regret to tell you, is frequently not “the animals” — though zoos and aquariums have, since the mid-20th century, marketed themselves as both tourist attractions and important players in wildlife education and conservation.   As my colleague Kenny Torrella writes, these institutions and their defenders argue they protect animals in three ways: first, by raising money for wildlife conservation projects; second, by helping to reintroduce vulnerable species back into the wild; and third, by inspiring visitors to take an interest in the environment. The Shedd Aquarium’s motto, for instance, is “For Love of Waterkind.”  It’s worth scrutinizing those purported virtues, however — even when prestigious and reputable institutions like Shedd are making them. On one hand, there is merit to the claim that zoos and aquariums fundraise for wildlife conservation: In 2022, the latest year for which data is available, one group of accredited zoos and aquariums spent more than a quarter of a billion dollars on habitat projects.  The evidence is thinner on the other points, though. It’s incredibly rare for aquariums and zoos to reintroduce endangered species back into the wild — that’s very difficult to do. And surveys of zoo and aquarium visitors show that merely seeing a wild animal in a tourist setting doesn’t generally galvanize people on matters of welfare or stewardship. Living in captivity in that tourist setting, however, can be stressful (or worse) for the animals themselves.  But what would a humane alternative look like? Even if zoos and aquariums stopped catching animals in the wild, that would still leave many thousands who are injured, orphaned, born in captivity, or otherwise accustomed to human care.  When it comes to whales, one nonprofit advocacy organization is already working on an alternative: a 110-acre coastal sanctuary for “retired” whales. That project, however, is still a long way from completion. And in the meantime, it’s up to consumers to decide whether the stated benefits of zoos and aquariums outweigh the potential harms to the animals they exhibit. One link for later ➨ Beware the trap of “moral perfection.” We should all endeavor to live lives that embody our values, sure. But if you never board a plane because you care about the climate, or you never take your kid to zoos because you read the arguments above, then you might end up with a smaller, less-lived life. And that’s no good, either.  Before you go… Did you know…that there have been “revolutionary” advancements in Alzheimer’s treatments in just the past five years? Two new drugs both markedly slow the progress of dementia. Today’s trivia: Geography time! What country is bordered by Chad to the east and Mali to the west?
