plain

Plain fluorescent magnetic poly(lactic acid) particles (PLA-M-greenF or -redF) have no special functional groups on the surface. They are available with mean diameters of 30 µm and 100 µm (broader size distributions) and with red fluorescence (PLA-M-redF, excitation: 552 nm, emission: 580 nm) or green fluorescence (PLA-M-greenF, excitation: 475 nm, emission: 510 nm).
The particles are supplied in water without any surfactants.
