Red fluorescent silica particles, carboxyl function

Red Fluorescent and carboxylic acid functional Silica Particles:

Nanocs offers a number of Red fluorescent and multifunctional silica nanoparticles and microbeads with particle size ranging from 50 nm to 12 microns. Our proprietary synthetic methods ensure the strong fluorescent signal, high photostability of these fluorescent beads. These red fluorescent particles have excitation/emission wavelength around 546 nm/575 nm. On the other hand, carboxylic acid groups on these fluorescent beads can be used to react with other groups. These particles have wide applications in flow cytometry, lateral flow assay, gene sequencing and many other bioassay development. These fluorescent multifunctional particles can include various fluorescent dyes from UV region to near IR, include coumarin, fluoresceins, rhodamines, cyanine dyes, alexa fluor dyes. Customer conjugation and modification is available upon request.
