Abstract

A single-step formation process has been developed for water-soluble, highly biocompatible, red-emitting silicon nanocrystals (Si-nc) by using pulsed laser irradiation of porous silicon in an organic solution. The obtained Si-nc shows excellent aqueous dispersibility and high photo- and pH-stability due to robust surface hydrophilic terminations. The Si-nc also has low cytotoxicity due to the biocompatibility of silicon and continues to exhibit a bright red luminescence after incubation with neuroblastoma cells. These properties make the present Si-nc a promising candidate for fluorescent labelling in cellular imaging. More information can be found in the Full Paper by Toshihiro Nakamura et al. on page 1137 in Issue 9, 2019 (DOI: 10.1002/cnma.201900289).
