Color-tunable bioluminescence imaging portfolio for cell imaging
Scientific Reports, 2021 The present study describes a color-tunable imaging portfolio together with twelve novel coelenterazine (CTZ) analogues. The three groups of CTZ analogues create diverse hues of bioluminescence (BL) ranging from blue to far red with marine luciferases ...

Let There be Light! Light as an Engine and Regulator in Synthetic Cells
Angewandte Chemie International Edition, Volume 65, Issue 24, 8 June 2026.Cells are out‐of‐equilibrium systems that regulate their spatiotemporal features. In biomimetic synthetic cells, light offers a unique way for energizing and regulating events in space and time. This review explores the implementation of light‐responsive tools in synthetic cells to replicate biological functions and enable new bioinspired behaviors ...

Bioluminescence Monitoring of Neuronal Activity in Freely Moving Zebrafish Larvae
Bio-Protocol, 2017 The proof of concept for bioluminescence monitoring of neural activity in zebrafish with the genetically encoded calcium indicator GFP-aequorin has been previously described (Naumann et al., 2010) but challenges remain.

Nanodiamond Quantum Sensors for Probing Free Radical Biology
Advanced Functional Materials, Volume 36, Issue 45, 5 June 2026.Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Luciferase-Specific Coelenterazine Analogues for Optical Contamination-Free Bioassays
Scientific Reports, 2017 Spectral overlaps among the multiple optical readouts commonly cause optical contamination in fluorescence and bioluminescence. To tackle this issue, we created five-different lineages of coelenterazine (CTZ) analogues designed to selectively illuminate ...

Advanced Science, Volume 13, Issue 33, 15 June 2026.This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Blue fluorescent protein from the calcium-sensitive photoprotein aequorin: Catalytic properties for the oxidation of coelenterazine as an oxygenase [PDF]
, 2006 Blue fluorescent protein from the calcium-binding photoprotein aequorin (BFP-aq) is a complex of Ca2+-bound apoaequorin and coelenteramide, and shows luminescence activity like a luciferase, catalyzing the oxidation of coelenterazine with molecular ...
