FABRICATION AND CHARACTERIZATION OF POROUS SILICON PARTICLES OF PLANT ORIGIN AND SILVER FOR THERANOSTICS

Annotation. Photoluminescence of bamboo and horsetail porous silicon (PS) particles was demonstrated for the first time, allowing visualization of cellular structures. It was shown that PS is capable of adsorbing drug molecules and releasing them during its degradation in solutions with a pH above 7. Using nifuroxazide as a test drug loaded into PS particles, its prolonged antibacterial activity against E. coli was found in comparison with pure nifuroxazide. Also, Ag/PS particles in combination with SERS spectroscopy allowed studying the molecular composition of bacteria.
