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 ...

A Review on MXene Terminations

open access: yesAdvanced Functional Materials, EarlyView.
Surface terminations play a decisive role in determining the properties of MXenes. Their coordination, composition and stoichiometry can be tuned both during synthesis and through post synthesis methods to tailor MXenes for optimum performance in applications. This review explores the present understanding of surface terminations.
