Probing skin photoallergens in reconstructed human epidermis: An EPR spin trapping investigation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 275-281, March/April 2025.
We present an original proof‐of‐concept methodology to probe radical generation from allergens in contact with photoexposed skin, using electron paramagnetic resonance and spin trapping in a reconstructed human epidermis model mimicking real‐life exposure scenarios.

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Performance comparison of pressure swing adsorption and amine‐based absorption for synthesis gas purification

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 5012-5027, September 2026.
Comparison of PSA and amine‐based absorption for syngas purification shows that PSA offers lower energy intensity, global warming potential, and minimum selling price, making it a more sustainable option. However, absorption achieves higher syngas purity. A GREENSCOPE‐based multi‐criteria assessment guides optimal process selection.

No Significant Secondary Structural Change of α‐Synuclein Monomer by Site‐Specific DOPA or Phosphorylation Introduction in Its C‐Terminal Region

Journal of Peptide Science, Volume 32, Issue 9, September 2026.
Site‐specifically modified α‐synuclein containing DOPA or phosphorylation was prepared by ligation of a bacterially expressed N‐terminal polypeptide and a synthetic C‐terminal modified peptide. ABSTRACT α‐Synuclein (αSyn) is a major component of pathogenic Lewy bodies and Lewy neurites and is closely associated with Parkinson's disease.

Human Leukocyte Elastase Triggered Nanoparticles for Targeted Antimicrobial Delivery and Oral Microbial Modulation

Advanced NanoBiomed Research, Volume 6, Issue 8, August 2026.
This study explores enzyme‐responsive nanoparticles for targeted antimicrobial release in inflamed oral environments. Nanoparticles formed by complexing peptides and chlorhexidine respond to human leukocyte elastase and release chlorhexidine selectively. P7 (ECAAPVCE)‐based formulations show optimal properties and stability, with antimicrobial activity
