Abstract
The methods, systemsand apparatus disclosed herein concern metalimpregnated porous substrates. Certain embodiments of the invention concern methods for producing metal-coated porous silicon substratesthat exhibit greatly improved uniformity and depth of penetration of metaldeposition. The increased uniformity and depth allow improved and more reproducible Raman detection of analytes. In exemplary embodiments of the invention, the methods may comprise oxidation of porous silicon, immersion in a metal salt solution, drying and thermal decomposition of the metal saltto form a metal deposit. In other exemplary embodiments of the invention, the methods may comprise microfluidic impregnation of porous silicon substrateswith one or more metal salt solutions. Other embodiments of the invention concern apparatus and/or systemsfor Raman detection of analytes, comprising metal-coated porous silicon substratesprepared by the disclosed methods.
