Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, Volume 4, Issue 2, June 2026.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Light Meets Nature: Cellulose Cluster as a Natural Photoantimicrobial Agent

Small Structures, Volume 7, Issue 6, June 2026.
Cellulose derivatives exhibit cluster‐triggered emission, generating singlet oxygen through long‐lived excitonic states without conventional chromophores. This work reveals strong photoantimicrobial activity against Gram‐positive bacteria, transforming cellulose from an inactive excipient into an effective photodynamic agent.

Aging Impairs Macrophage Phagocytosis Through Mitochondrial ROS‐Induced Collagen Production

Aging Cell, Volume 25, Issue 6, June 2026.
Aging compromises macrophage phagocytosis via the mitochondrial ROS‐driven overproduction of intracellular collagen. This excess collagen physically binds F‐actin, paralyzing cytoskeletal turnover; however, mtROS scavenging successfully rescues actin dynamics and restores phagocytic capacity.

Multifiber Array‐Based Photometry System for Multiregional Functional Mapping in the Mouse Brain

European Journal of Neuroscience, Volume 63, Issue 12, June 2026.
Existing fiber photometry approaches suffer from invasiveness and limited scalability. A newly developed multifiber array‐based photometry system allows targeting multiple brain regions with less invasiveness. The system was validated in two jGCaMP8s‐expressing mouse lines by monitoring GABAergic neural population activity across multiple brain regions
