Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, Volume 4, Issue 3, September 2026.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Protein‐Stabilized Copper Nanoclusters for Microbial Inhibition‐Enabled Fresh Produce Preservation and Pesticide Removal

cMat, Volume 3, Issue 3, September 2026.
Biocompatible bovine serum albumin‐stabilized copper nanoclusters (Cu@BSA NCs) were engineered to integrate potent antimicrobial activity with efficient pesticide adsorption. The dual mechanism, involving Cu species/ROS‐mediated microbial inactivation and BSA‐facilitated pesticide capture, enables simultaneous extension of fresh produce shelf‐life by ≥

Synthesis and screening of N-acyl thiolated chitosans for antibacterial applications [PDF]

Carbohydrate Polymers, 2016
Low-molecular weight chitosan-thioglycolic acid has shown significant antibacterial properties against different microorganisms. In order to explore the potential and structure-activity relationships of newly synthesized alkyl thiomers, chitosan has been functionalized with a series of thio-acids with increasing alkyl chain length.

Electrochemical Sensors for Heavy Metal Ion Detection: Principles, Advances, and Challenges

Electroanalysis, Volume 38, Issue 9, September 2026.
Required conditions for the electrochemical detection of specific heavy metal ions in reusable electrodes by a real liquid sample with interfering ions. The continuous discharge of heavy metal ions resulting from intense industrial activity into the environment poses risks to all life on Earth (high toxicity and bioaccumulation).

Synthesis of Thiolated Chitosan as Matrix for the Preparation of Metformin Hydrochloride Microparticles [PDF]

, 2015
Thiolated chitosan is synthesized by reacting chitosan and cysteine as the carriers of thiol groups with 1-ethyl-3-(3-dimethylamino propyl) carbodiimide (EDAC) as catalyst. The properties of thiolated chitosan was then characterized, and being formulated
