Beads & Microspheres

Nanocs provides a number of different sized silica particles coated with a thin layer of gold on their surface. Thickness of this gold layer ranges from 20-100 nm. These gold coated silica particles have high affinity toward proteins, antibodies, peptides and nucleic acids. With their high affinity to biomolecules, our gold coated silica particles can be used for biomolecule and cell detection, purification and separation.

Carboxyl functionalized silica nanoparticles or micro beads from Nanocs have narrow size distribution yet with multiple size selection from 5 nm to 50 microns. Carboxylic acid groups on these silica beads can be activated by EDC and they can easily react with primary amine groups. Nanocs functional silica nanoparticle or micro beads are suspended in 1% aqeuous solution. Standard deviation of these silica particles is in the range of 10% of listed size parameter. Nanocs also offers various fluorescently labeled and surface functionalized silica particles for wide biomedical research and bioassay development. These surface modified silica particles provide our customers with more choices for in-vitro or in-vivo applications of those nanoparticles.

Nanocs offers a number of Fluorescent silica nanoparticles and silica microbeads with fluorescent signal from UV region to near infrared area. Fluorescein labeled silica beads are green fluorescent particles with excitation/emission wavelength around 490 nm/515 nm. Silica particles from Nanocs have narrow size distribution yet with multiple size selection from 7 nm to 50 microns. These particles are suspended in 1% aqeuous solution. Standard deviation of these particles is in the range of 10~20% of listed size parameter. These particles have wide applications in diagnostic reagents and bioassay development. They can be further modified with different surface coatings and functional groups. Nanocs fluorescent labeled silica particles provide more choices for in-vitro or in-vivo applications of those nanoparticles. These particles include various fluorescent dyes from UV region to near IR, include coumarin, fluoresceins, rhodamines, cyanine dyes, alexa fluor dyes. Customer conjugation an
