Caption

Left: Schematic representation of silicon nanoparticles (SiNPs) biodegradation processes: (I) localization of SiNPs on the cell membrane; (II) penetration of SiNPs in the cytoplasm with partial solubility of the nanoparticles; (III) strong dissolution of SiNPs after 10-13 days within the cell body. Right: Raman spectra of SiNPs for different incubation times: 9 h, 48 h and 13 days of incubation depicted in red, blue and green, respectively. Inset: corresponding xz-cross-section of Raman spectroscopy images of MCF-7 cells cultivated with SiNPs.
