Developing giant plasma membrane vesicles from Leishmania cells to investigate the role of membrane proteins in photodynamic inactivation

open access: yesPhotochemistry and Photobiology, EarlyView.
In this study, we developed giant plasma membrane vesicles (GPMVs) from Leishmania amazonensis promastigote membranes to investigate the role of protein‐embedded membranes in methylene blue (MB) photooxidation. Upon MB photoactivation in model lipid membranes (giant unilamellar vesicles, GUVs), a distinct photooxidation effect was observed, marked by ...

Germicidal potential and skin compatibility of an innovative UVC phototherapy device emitting at 234 nm

open access: yesPhotochemistry and Photobiology, EarlyView.
A phototherapy device emitting principally at 234 nm was assessed for antimicrobial efficacy against Methicillin‐resistant Staphylococcus aureus and evaluated for skin health hazards. Abstract Chronic wounds are a major healthcare issue affecting more than 10 million Americans each year, with a 5‐year survival similar to cancer and costing the ...

Photo‐Responsive Glyco‐Microfibers: Design, Self‐Assembly, and Morphological Control of Aqueous Microdroplets

open access: yesChemSystemsChem, Volume 8, Issue 2, March 2026.
Aqueous self‐assembly of a 2‐nitrobenzyl‐functionalized glucosamine derivative leads to the formation of photo‐responsive glyco‐microfibers via cooperative noncovalent interactions, primarily driven by π–π stacking and hydrogen bonding. Upon photo‐irradiation, the glyco‐microfibers undergo dis‐assembly even within confined water‐in‐oil microdroplets ...

Dynamical Instability and Expansion-free Condition in $f(R,T)$ Gravity

open access: yes, 2015
Dynamical analysis of spherically symmetric collapsing star surrounding in locally anisotropic environment with expansion-free condition is presented in $f(R,T)$ gravity, where $R$ corresponds to Ricci scalar and $T$ stands for the trace of energy ...

Push–Pull Bridged Stilbenes as Small Solvatochromic Aggregation‐Induced Emission Luminogen: Design and Excited‐state Deactivation Dynamics

open access: yesAggregate, Volume 7, Issue 2, February 2026.
A push–pull bridged stilbene (DpCBS[7]) demonstrates both solvatochromism and aggregation‐induced emission (AIE) within a compact molecular framework. Despite polarity‐dependent emission shifts, its fluorescence quantum yield remains low in solution due to ultrafast internal conversion.

Dual‐Channel Fluorescence Assays with Supramolecular Host‐Dye Reporter Pairs for Membrane Activity Mapping of Peptides

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Membrane‐active peptides (MAPs) such as cell‐penetrating peptides (CPPs) and antimicrobial peptides (AMPs) can translocate across lipid membranes and create membrane pores. The combination of a dye efflux and a supramolecular tandem membrane assay in a dual‐channel format enables an advanced mechanistic characterization and an exploration of the ...
