Abstract
AbstractHere we present a simple and effective method to fabricate porous silicon photonic crystal‐based hybrid particles by soft lithography. These fabricated hybrid particles are composed of pristine porous silicon structures strengthened by a polymer infused nanocomposite framework. The pristine porous silicon moiety serves as a sensor because of its environmentally sensitive optical features, while the polymer‐infused moiety provides a mechanically resilient scaffold and its invariant optical features can be used as an optical barcode and a built‐in self‐reference for optical sensing.
