Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles
Advanced Materials, EarlyView.This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

Advanced Materials Interfaces, EarlyView.The gas‐phase decomposition of Al(acac)3 is investigated under inert, oxygen, and water‐containing conditions. Water is found to promote selective ligand removal and suppress hydrocarbon formation, while oxygen induces faster, less selective decomposition pathways.

An Advanced Molecularly Imprinted Polymer‐Based Electrochemical Aptasensor for Carbendazim Detection
Advanced Materials Interfaces, EarlyView.A dual‐recognition electrochemical aptasensor that integrates a molecular imprinted polymer (MIP) and an aptamer is developed for the detection of a common pesticide, carbendazim (CBZ). The resulting sensor exhibits enhanced selectivity toward CBZ over structurally similar compounds and achieves a low detection limit of 1.3 nm, demonstrating its ...
