Properties of Human Serum Albumin Entrapped in Sol−Gel-Derived Silica Bearing Covalently Tethered Sugars

Silica derived from biocompatible silane precursors and containing covalently bound sugar moieties has recently been reported to be a much more biocompatible matrix for protein entrapment than any previously synthesized materials. To better understand the nature of these new materials, the steady-state and time-resolved fluorescence of human serum albumin (HSA) was used to examine the conformation, dynamics, accessibility, thermal stability, …
