Metronidazole‐Loaded Cyclodextrin Nanogels for Antibacterial Therapy and Microbiota Regulation in Periodontitis

Advanced Healthcare Materials, EarlyView.
A methacrylamide β‐cyclodextrin‐based nanogel (MACD nGel) is developed to load the antimicrobial drug Metronidazole (MNZ) for topical delivery for the treatment of periodontitis. It is demonstrated that cyclodextrin nanogel (nGel) loaded with metronidazole provides an efficient drug delivery route but also has potential clinical applications and offers

Preliminary Study of a Ninj1‐Loaded Bimodal Ultrasound/NIR Fluorescence Targeted Molecular Probe for Diagnosing Early‐Stage Inflammation in Coronary Microvascular Dysfunction

Advanced Healthcare Materials, EarlyView.
Coronary microvascular dysfunction (CMD) targeting remains a challenge for precise diagnosis. This work presents a dual‐modal nanoprobe (T‐IR780‐NBs) that combines ultrasound contrast with near‐infrared fluorescence. This technology utilizes proteomics‐derived antibodies that specifically localize to inflamed and injured cardiac tissue, enabling ...

Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

Advanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...
