Functional Diversity and Oleaginous Potential of Fungal Strains From Hawaiian Soil Ecosystems

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Fungi represent an important but underexplored resource for microbial lipid production, including nutritionally valuable polyunsaturated fatty acids. Hawaiian soils, shaped by volcanic parent materials and strong environmental gradients, provide a unique setting for discovering functionally diverse fungal strains with distinct metabolic traits.

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

BMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...

Electron compensation‐gated nanomotor for immunomodulation and microenvironment remodeling in bacterial pneumonia therapy

BMEMat, EarlyView.
A nanomotor featuring an “electronic lock” via electron compensation in an Au‐Ag alloy ensures therapeutic precision. Near‐infrared light acts as a key, unlocking on‐demand Ag+ release for synergistic bactericidal action and microenvironment remodeling to potently treat bacterial pneumonia. Abstract Bacterial pneumonia treatment is severely hampered by
