Toward homochiral protocells in noncatalytic peptide systems

, 2009
The activation-polymerization-epimerization-depolymerization (APED) model of Plasson et al. has recently been proposed as a mechanism for the evolution of homochirality on prebiotic Earth.

Synthetic Studies Towards Darobactin A

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
The urgent need for new antibiotics led us to develop a new methodology for the synthesis of the natural product darobactin A selectively targeting gram‐negative bacteria. This study provides new insights into the synthesis of strained indole‐containing macrocycles.

Smart Wearable Ozone Therapy System for Managing Multidrug‐Resistant Wound Infections

Advanced Therapeutics, Volume 9, Issue 3, March 2026.
A smart wearable ozone therapy system enables precise localized ozone delivery directly to the wound bed through integrated ozone generation, real‐time sensing, and controlled air circulation. Controlled ozone exposure disrupts bacterial membranes, enhances antibiotic accessibility, and supports a clinically translatable strategy for managing multidrug‐

Atomically Precise Clusterzymes: A Programmable Optoelectronic Platform for Neuroscience

Advanced Science, Volume 13, Issue 16, 18 March 2026.
Atomically precise clusterzymes, engineered via atomic and ligand design, serve as programmable platforms for neuroscience applications. They demonstrate tailored biocatalysis for neuroinflammation, tunable optical properties for deep‐tissue bioimaging and 3D visualization, and enhanced charge transfer for brain–computer interfaces.

From Solution to Surface: How the Catalytic Environment Modulates Peptide Bond Cleavage by Metal‐Oxo Cluster Nanozymes

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Comparison of homogeneous Hf12(sol) and heterogeneous Hf12(precip) metal‐oxo clusters enables investigation of how solubility influences nanozymatic reactivity and selectivity toward proteolysis, without introducing confounding factors from differences in cluster identity.

Photoisomerization in Cyclic Dipeptide Derivatives: Photoswitchable Supramolecular Hydrogels and the Discovery of Hemipiperazine Photoswitches

ChemPhotoChem, Volume 10, Issue 3, March 2026.
Photoswitchable cyclic dipeptides (CDPs) can be used to prepare hydrogels that reversibly dissipate upon irradiation, or to photomodulate the development of living organisms. We report here applications and perspectives for CDPs containing azobenzene photoswitches or newly discovered hemipiperazine photoswitches in smart materials and biological ...

Metaproteome Analysis of Short‐Term Thermal Stress in Three Sympatric Coral Species Reveals Divergent Host Responses

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Short‐term thermal stress triggers distinct molecular responses in three sympatric coral species with contrasting thermal resilience. Proteomic and metabolomic profiling reveal both species‐specific and limited shared pathways underlying these stress responses.
