The quantitative analysis of molecule interactions in bioimaging is key for understanding the molecular orchestration of cellular processes and is generally achieved through the study of the spatial colocalization between the different populations of molecules. Colocalization methods are traditionally divided into pixel-based methods that measure global correlation coefficients from the overlap...
A new colorimetric and fluorescent probe was reported, which can be used in a very low dosage (<20 nM) for rapid, highly selective and sensitive detection of biothiols.
We report the facile synthesis of carbon dots with tunable fluorescence from unzipping of photonic crystals and their application in LEDs, which may provide an insight into the creation of multifunctional carbon dots adapted for various applications such as in optoelectronics, sensing, or bioimaging.
Methods of optical bioimaging and neuroimaging are rapidly evolving and penetrate both to experimental laboratories and clinics. Among their advantages are non-invasiveness and abilities varying from multiscale image acquisition to functional real-time imaging. This Special Issue presents a collection of papers contributed by the leading groups in bioand neuroimaging depicting their state-of-th...
We describe here hitherto unexplored chemistry of the sulfinate ester functional group as being highly selective towards nucleophilic substitution by thiols at physiological pH. Using this cleavable trigger, an optical thiol probe that is suitable for thiol bioimaging has been developed.
Strongly fluorescent graphene quantum dots (GQDs) have been prepared by one-step solvothermal method with PL quantum yield as high as 11.4%. The GQDs have high stability and can be dissolved in most polar solvents. Because of fine biocompatibility and low toxicity, GQDs are demonstrated to be excellent bioimaging agents.
A dual fluorophore-based color-tunable molecular beacon visualized the microRNA-294 expression-dependent color change in cells.
Fluorescent silica nanoparticles deposited with highly monodisperse gold nanoparticles (1-2 nm) were synthesized via the W/O method and intensive ultrasound irradiation. A large surface area of gold-doped fluorescent silica nanoparticle serves as a platform to immobilize a specific binding protein for biomolecules interaction in bioimaging applications.
We demonstrate a facile approach for converting AgCl to functional silver nanoparticles (AgNPs) via photoreduction in the presence of DNA. The resulting AgNPs are biofunctionalized, and exhibit photostable luminescence and DNA-specific Raman signatures, showing high potential for use in DNA-directed recognition and advanced bioimaging.
