Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions
Advanced Materials, EarlyView.This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

Dextran Nanoparticle Synthesis and Properties
, 2016 Dextran is widely exploited in medical products and as a component of drug-delivering nanoparticles (NPs). Here, we tested whether dextran can serve as the main substrate of NPs and form a stable backbone. We tested dextrans with several molecular masses

A Critical Review on the Evolution of Chitosan‐Based Injectable Hydrogels in Bone Regeneration
Advanced Materials Interfaces, EarlyView.The graphical illustration depicts hydrogel formulation using chitosan and biocompatible cross‐linkers, major advantages, and incorporation of cells, osteoinductive factors, and therapeutic drugs. Following injection, pH‐responsive gelation enables controlled drug release, promotes cell recruitment and osteogenic differentiation, enhances extracellular

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites
Advanced Materials Technologies, EarlyView.Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.
