摘要
beta-Glucuronidase enzymes have been attached to a porous silicon surface through a direct silicon-carbon bond based linking system (see Figure). The attached enzymes display high activity and the photoluminescent (PL) properties and surface stability of the porous silicon are retained. Quenching of the PL is observed upon enzymatic breakdown of the substrate, leading to the possibility of a new class of chemical and biological sensors.
