Abstract

We report the incorporation of porous silicon on paper towards the realization of a low-cost rapid diagnostic testing platform with the capability for quantification of detected molecules. Real-time optical reflectance measurements of bovine serum albumin adsorption were carried out to benchmark the sensor. Simulations and experiments demonstrate a response-time dependence on porous silicon pore size. Approaches to overcome challenges with porous silicon adhesion on paper and porous silicon membrane mechanical robustness will be discussed.
