Characterization and Antimicrobial Activity of Hafnium Nanostructures Fabricated by Physical Vapor Deposition Through a Colloidal Mask

Advanced Materials Interfaces, EarlyView.
We generate hafnium nanostructures by first depositing polystyrene particles of varying diameter followed by physical vapour deposition of hafnium thin films. The resultant structure shows a kill‐on‐contact effect against both Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus.

Efficient Self‐Cleaning and Anti‐Bacterial Behavior Realized by Hierarchical Structure in Hybrid Waterborne Polyurethane Coatings Containing Photocatalyst

Advanced Materials Interfaces, EarlyView.
Hybrid WPU coatings with a hierarchical structure are constructed by first directional freezing polymerization of degradable hydrogels with a vertical channel structure and then filling these channels with aqueous WPU solution containing carbon nitride (g‐C3N4) nanosheets.

Antimicrobially active microorganisms associated with marine bryozoans [PDF]

, 2011
Bryozoans are sessile colonial animals that can be found in various aquatic and mainly in marine environments. Due to their sessile nature, bryozoans compete for surfaces they can colonize but, on the other hand, are confronted with microbial colonizers ...

Electrochemically Engineered PEDOT:PSS/MXene Composite Electrode for the Label‐Free Procalcitonin Detection

Advanced Materials Interfaces, EarlyView.
Procalcitonin is a key biomarker for bacterial infections, but conventional detection methods are often time‐consuming. Here, we present an electrochemical sensor based on highly conductive Ti3C2Tx MXene combined with PEDOT:PSS, enabling direct antibody immobilization, while a bovine serum albumin coating provides antifouling protection.
