Cantilever-based Resonant Gas Sensors with Integrated Recesses for Localized Sensing Layer Deposition [PDF]

, 2013
This work presents mass-sensitive hammerhead resonators with integrated recesses as a gas-phase chemical microsensor platform. Recesses are etched into the head region of the resonator to locally deposit chemically sensitive polymers by ink-jet printing.

A facile strategy to synthesize poly(methyl methacrylate)-co-polyisobutylene via a deoxygenation reaction

eXPRESS Polymer Letters
Poly(methyl methacrylate) or PMMA is a versatile material because of its ease of manipulation and biocompatibility. However, brittleness limits its applications; hence, copolymerization of PMMA with rubber such as polyisobutylene (PIB) is required.
