CD Bioparticles provides large selection of uniform poly(methyl methacrylate) (PMMA) micro- and nanoparticles with multiple sizes from 25 nm to 750 µm. Our PMMA particles are highly spherical, optically clear, and can be dissolved with solvents. PMMA particles are more hydrophilic, amorphous, transparent and colorless thermoplastic that has an excellent UV resistance. The sizes of particles are determined by photon correlation spectroscopy, scanning electron microscope or laser diffraction. Our PMMA particles can be applied for a variety of applications, including drug delivery, bioimaging and biomedical devices.
