Engineering Magnetotactic Bacteria as Medical Microrobots

Advanced Materials, EarlyView.
Magnetotactic bacteria (MTB) are living microorganisms that produce magnetosomes for navigation using the Earth's geomagnetic field. Their built‐in magnetic components, along with their intrinsic and/or modified biological functions, make them one of the most promising platforms for making future living and programmable microrobots.

Stress Response of Aspergillus niger Spores to Copper Surfaces and the Implications for Antifungal Surface Functionalization

Advanced Materials Interfaces, EarlyView.
This study investigates the antifungal efficacy of ultrashort pulsed laser‐induced periodic surface structures (USP‐DLIP) on copper, brass, and steel surfaces. Using Aspergillus niger as a model, the research highlights a 99% reduction in spore viability on 9 µm structured copper surfaces due to enhanced copper ion release. Scanning electron microscopy

Triarylphosphonium BODIPY‐Based [2]Rotaxanes Nanoparticles for Light‐Driven Antibacterial Applications

Advanced Optical Materials, EarlyView.
New photosensitizers for light‐induced antimicrobial therapy are successfully synthesized and characterized. When dissolved in water, all compounds self‐assemble forming spherical aggregates with <100 nm dimensions. The nanoparticles show high photothermal conversion efficiency and demonstrate antimicrobial activity toward both Gram‐negative and Gram ...

Antibiotic–Polycationic Peptide Conjugation as an Effective Strategy to Overcome Daptomycin Resistance

Advanced Therapeutics, EarlyView.
Antimicrobial resistance necessitates the development of new antibiotics with “resistance‐breaking” properties. In this study, conjugation of polycationic peptides is proven to represent a versatile strategy for the fast and affordable reactivation of daptomycin.
