Heterocyclic silanes containing Si-N or Si-S bonds in the ring undergo a opening reaction with -OH groups at surface of porous Si nanostructures to generate -SH -NH functional surfaces, grafted via O-Si bonds. The is substantially faster (0.5-2 h 25 °C) and more efficient than hydrolytic condensation trialkoxysilanes on similar hydroxy-terminated retains open pore structure photoluminescence quantum-confined silicon nanostructures. chemistry sufficiently mild allow trapping test protein lysozyme, which its enzymatic activity upon release from modified nanostructure.
