Fluorescent magnetic poly(lactic acid) particles
combine separation and detection purposes,
consist of magnetite (40% w/w) in a matrix of poly(D,L-lactic acid) with a molecular weight of 17.000 Da,
are available with mean diameters of 30 µm and 100 µm (broader size distributions),
are offered with red fluorescence (-red, excitation: 552 nm, emission: 580 nm) or green fluorescence (-green, excitation: 475 nm, emission: 510 nm),
can be loaded with drugs on request.
