Electronic (also called chemiresistive) gas sensors based on semiconducting metal oxides (SMOX) are widely used to detect hazardous gases for environmental, health and safety monitoring, including industrial processes and air quality assessment, among others.  However, volatile siloxanes, which are organosilicon compounds prevalent in personal care products and other consumer materials, can severely degrade the performance of these sensors (so-called siloxane poisoning), eventually leading to their failure.To address this vulnerability, UC Berkeley researchers have developed an effective mitigation strategy that applies an ultra thin protective layer over the sensing material. This barrier effectively suppresses siloxane induced deactivation by altering the adsorption energetics and reaction pathways of the interferents. The interfacial electronic interactions and protection mechanisms have been comprehensively validated through density functional theory calculations and rigorous material characterization techniques, offering a robust framework for designing resilient environmental sensors.

Long term wear of corrective eyewear often causes discomfort, dry eyes, and lipid accumulation due to the hydrophobic nature of standard lens materials. To alleviate these issues and improve user comfort, UC Berkeley researchers have developed an innovative manufacturing method to synthesize surface modified soft contact lenses. The technique involves contacting a standard soft contact lens with a functionalized hydrophilic polymer that contains a specific reactive group. When activated under controlled environmental conditions, this reactive group forms a robust covalent bond directly with the surface of the lens body. This process creates a stable, surface confined hydrophilic polymer layer that significantly enhances water retention and biocompatibility without altering the underlying optical properties and oxygen permeability of the lens material.
