Researchers use silicon nanoparticles for bioimaging and drug delivery

An international research team has studied a new cell visualisation and drug delivery system based on nanoparticles coated with luminescent dye molecules. The particle material and the distance between the dye and the particle's surface affect the intensity of the luminescent signal. Silicon nanoparticles coated with dye molecules are more efficient than similar particles made of gold. Thanks to their biocompatibility, silicon particles can be used for cell visualisation and drug delivery. The research was published in Scientific Reports.
