Summary: Small-molecule based fluorescent probes play an increasingly important role in detecting and imaging biological signaling molecules due to their simplicity, high selectivity, and real-time analysis capabilities. Various sensing mechanisms, including FRET, ICT, PeT, ESIPT, AIE, as well as dual/triple sensing mechanisms, are highlighted, but challenges remain. Future development should focus on improving small-molecule fluorescent probes for biosensing applications.

Summary: In this study, the anisotropic light emission from fluorescent Janus emulsion droplets was investigated. The experimental observations showed that the morphology-dependent optical confinement of emitted light contributed to the droplets' anisotropic light emission profile. Through ray-tracing, the optical properties of the droplets were predicted and fine-tuned to enhance their ability to concentrate light. A ratiometric dual-angle fluorescence detection approach was implemented, and it quantified the chemically-induced modulation of the anisotropic emission of droplet layers. The findings demonstrated that dye-loaded Janus emulsion droplets function as stimuli-responsive, tunable, fluorescent optical elements.

Summary: Real-time monitoring of cellular environment, such as intracellular pH, in a defined cellular space provides a comprehensive understanding of dynamic processes in living cells. By assembling multiple fluorophores within a space smaller than the spatial resolution of conventional microscopy, a flexible combinatorial design strategy for developing fluorescent probes is enabled. Assembling fluorescein (CF) and tetramethylrhodamine (CR) on a DNA nanostructure with controlled numbers of each fluorophore type allows for controlled fluorescence emission intensity and ratiometric pH monitoring within the defined space.

Summary: The morphology of metallacycle-cored supramolecular polymers can be finely controlled by the length of PEG and the choice of solvent. In methanol, rod-like or sheet structures are formed, while in tetrahydrofuran, thin films, vesicles, and nanorings can be observed based on the length of PEG.

Summary: Single-cellwestern blotting (scWB) is a common method for high-resolution protein analysis on low-abundance cell samples. However, antibody stripping during repeated staining leads to signal loss, preventing multiplex protein detection. In this study, we introduce Fluorescent-quenching Aptamer-based Single-cell Western Blotting (FAS-WB) for multiplex protein detection at single-cell resolution. FAS-WB allows rapid penetration, diffusion, and elution of aptamer probes, while avoiding signal loss through the use of fluorophore-tagged aptamers coordinated with quenching strands.

Summary: The vibrationally resolved pyrene fluorescence probe method has become less popular due to limited sensitivity and concentration independence. However, the recent discovery of a pyrene acylhydrazone with concentration- and polarity-dependent fluorescence spectra has provided a powerful vibrationally resolved spectrum probe.

Summary: The combination of electrophysiology and optogenetics has led to the development of a highly scalable neural probe that overcomes spatial limitations of nanophotonic circuits, allowing for a significant increase in sensor density. This advancement was achieved through a novel strategy of coupling only one waveguide to multiple optical ring resonators as passive nanophotonic switches.
