Unusual Thermally Induced Blueshift and Emission Amplification of Mn2+ Ions Enable Filter‐Free Luminescent Thermal Imaging

Advanced Science, EarlyView.
ABSTRACT The shift from point‐based thermal sensing to filter‐free thermal imaging requires luminescent thermometers that exhibit pronounced and thermally driven spectral changes within spectral regions matching the sensitivity profiles of the red, green and blue (RGB) channels of a digital camera.

CD177 Deficiency Defines a Stable Subtype of Human Neutrophil Granulocytes with Tumor Promoting Activity

Advanced Science, EarlyView.
Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...

Localized Accumulation of Tri‐n‐Propylamine Prolongs Electrochemiluminescence for Tumor Model Spheroid Analysis

Angewandte Chemie, EarlyView.
Here, we enhance the electrochemiluminescence imaging of cellular spheroids using [Ru(bpy)3]2+/TPrA chemistry. Our strategy, which involves pre‐incubation with TPrA, enables high‐resolution, long‐term visualization of cellular spheroids without phototoxicity.
