Discriminative Analysis of NO Gases by Two-Dimensional Violet Phosphorus Field-Effect Transistors.

Two-dimensional violet phosphorus (VP) has emerged as a new sensing material in various sensing applications due to its unique electrical properties and high stability among allotropes of phosphorus. Currently, the research of the VP-based analysis method is at the early stage. In this work, a VP nanosheet-based field-effect transistor (FET) sensor is reported for the detection of NO and NO gases with extraordinary sensing performance.

3D bioprinted mesenchymal stromal cells in skin wound repair.

Skin tissue regeneration and repair is a complex process involving multiple cell types, and current therapies are limited to promoting skin wound healing. Mesenchymal stromal cells (MSCs) have been proven to enhance skin tissue repair through their multidifferentiation and paracrine effects. However, there are still difficulties, such as the limited proliferative potential and the biological processes that need to be strengthened for MSCs in wound healing.

Single-Atom Pt-Functionalized TiCT Field-Effect Transistor for Volatile Organic Compound Gas Detection.

MXenes have shown exceptional electrochemical properties and demonstrate great promise in chemiresistive gas analysis applications. However, their sensing applications still face low sensitivity and specificity, slow response, and poor stability among the many challenges. Herein, a novel synthetic approach is reported to produce single-atom Pt (Pt SA)-implanted TiCT MXene nanosheets as the sensing channel in field-effect transistor (FET) gas sensors.

HS sensing under various humidity conditions with Ag nanoparticle functionalized TiCT MXene field-effect transistors.

Despite the critical need to monitor HS, a hazardous gas, in environmental and medical settings, there are currently no reliable methods for rapid and sufficiently discriminative HS detection in real-world humid environments. Herein, targeted hybridizing of TiCT MXene with Ag nanoparticles on a field-effect transistor (FET) platform has led to a step change in MXene sensing performance down to ppb levels, and enabled the very high selectivity and fast response/recovery time under room temperature for HS detection in humid conditions. For the first time, we present a novel relative humidity (RH) self-calibration strategy for the accurate detection of HS.
