✦ Synopsis

Abstract

Functionalization of hydrofluoric acid‐etched crystalline silicon surfaces were performed using 4‐aminopyridine. This treatment was employed to perform an organic interface with the exterior ambient. The obtained treated surfaces were exposed to different organic vapors while keeping track of their electric conductance to assess their sensing abilities. Results for these tests are provided.

## Abstract A miniaturized, low‐power chemical sensor for volatile organic compounds using a porous Si photonic crystal is demonstrated. The device uses simple electronic circuitry a light‐emitting diode, a phototransistor, and thin film of a 1‐dimensional photonic crystal of porous Si, drawing 0.5

## Abstract Hydrophobic comonomers bisphenol‐A and hexafluorobisphenol‐A were incorporated as diol components in the sensor‐coating material poly(ethylene maleate) (PEM), resulting in modified polymers, HCPEM and HFPEM, respectively. To assess the suitability of these polymers as sensor interfaces,
