CD Bioparticles Launches Versatile Polystyrene Particles for Diverse Bioresearch

CD Bioparticles has introduced a groundbreaking series of Functional Polystyrene Particles, catering to the diverse requirements of the pharmaceutical and life science sectors. With a wealth of experience in these industries, the company's latest offering includes Functional Polystyrene Particles spanning diameters from 25 nm to 750 µm. This versatile range empowers researchers across various applications, including protein adsorption, immunoassays, bio separations, and drug delivery.

The synthesis of polystyrene particles involves both emulsion and emulsion-free polymerization processes. These particles can be further enhanced through coating or conjugation achieved by passive adsorption or covalent coupling. Functionalized polystyrene nanoparticles and particles find applications in drug delivery materials, bioimaging, markers, immunoassays, and provide a flexible platform for diagnostic and bio separation applications. Various methods, such as adsorption onto plain polystyrene particles, covalent attachment onto surface-functionalized particles, and adsorption onto pre-coated particles with binding proteins, are employed for ligand adsorption.

CD Bioparticles now presents an array of Plain Polystyrene Particles with diameters ranging from 25 nm to 750 µm, exemplified by products like DiagPoly™ Plain Polystyrene Particles, 0.025 μm (Cat. No. DMP-L001). These particles serve as standards or markers and find utility in immunoassays, latex agglutination assays, solid-phase enzyme immunoassays, and research and diagnostic tests. The meticulous control exercised by the company's skilled chemists ensures a precise monodisperse particle size distribution during the synthesis process.

Polystyrene particles possess a slight negative charge due to the surface charge resulting from initiator fragments employed in the polymerization reaction. Referred to as plain or neutral particles, these monodisperse polystyrene particles, also known as latex microspheres, serve diverse purposes such as immunodiagnostic assays, size standards for instrument calibration, and applications in cell biology.

The proprietary formulation and process technology employed by CD Bioparticles contribute to the production of microspheres with exceptional size uniformity. These polystyrene microspheres offer a flexible platform for diagnostic and bio separation applications, allowing for coating with recognition molecules such as antigens, antibodies, or peptides. Additionally, they can be loaded with hydrophobic dyes and other compounds.

The Plain Polystyrene Particles from CD Bioparticles boast a winning combination of versatility and performance. Beyond being non-toxic, odorless, and highly transparent, these microspheres exhibit a range of sizes, impressive stiffness, chemical resistance, and a remarkably uniform surface conducive to passive adsorption. Applications span from protein adsorption and diagnostic assays to electron microscopy, instrument calibration, and coating materials for contrast agents and anti-cancer drugs. The introduction of CD Bioparticles' Plain Polystyrene Particles caters to a spectrum of research needs, offering scientists a reliable and adaptable tool for diverse applications in the field.
