Block Copolymer Microcapsules with Perpendicularly‐Perforated Ultrathin Membranes for Controlled Transmembrane Transport

open access: yesAdvanced Functional Materials, EarlyView.
Block copolymer microcapsules with ultrathin, perpendicularly perforated membranes are developed through double emulsions, initiated by the diffusion of water into single emulsions. Both shell thickness and channel diameter can be systematically tuned, offering precision in molecular sieving and significantly enhanced permeation rates.

Wafer‐Scale Integration of α‐quartz Thin Films toward Super High Frequency Piezoelectric bioNEMS for Chikungunya Virus Detection

open access: yesAdvanced Functional Materials, EarlyView.
Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...
