Peptide‐Ligand Cooperative Interplay Drives Gold Nanoparticle Encapsulation by Protein Cages

open access: yesSmall, EarlyView.
Gold nanoparticle encapsulation within protein cages is governed by salt‐dependent binding energetics and cooperative peptide–ligand interactions. Ligands enhance electrostatic attraction while peptides extend recruitment and prevent kinetic trapping, enabling robust cargo loading. This molecular‐level insight links experiments and simulations, guiding

Forensic bruise documentation with alternate light sources: Preliminary observation on deceased individuals in a routine illuminated autopsy setting

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Alternate light sources (ALS) have been suggested to improve bruise visibility for medicolegal evaluations. Previous studies have recommended darkened conditions; however, this does not reflect real‐life autopsy settings, where multiple examinations are conducted simultaneously and turning off the lights is neither practical nor safe.
