Two novel vis-NIR pH probes based on styrylcyanine with acidic pH response are easily synthesized, which display large Stokes shift and high sensitivity. The significant colocalizations of two probes with LysoTracker Green DND-26 are achieved in C6 cells, suggesting potential application for imaging acidic organelles in live cells.

Mercury(II) is highly toxic thus the selective and sensitive detection of Hg(II) is important. This research article deals with the synthesis and characterization of the fluorogenic system based on diselenide containing rhodamine by single crystal XRD. The probe has been used for selective detection of Hg(II) in aqueous media with detection limit of 62.

Luminescent Lanthanide (III) (Ln(III)) bioprobes (LLBs) have been extensively used in the last two decades as intracellular molecular probes in bio-imaging for the efficient revelation of analytes, to signal intracellular events (enzymes/protein activity, antigen-antibody interaction), target specific organelles, and determine parameters of particular biophysical interest, to gain important insights on pathologies or diseases. The choice of using a luminescent Ln(III) coordination compound with respect to a common organic fluorophore is intimately connected to how their photophysical sensitization (antenna effect) can be finely tuned and especially triggered to respond (even quantitatively) to a certain biophysical event, condition or analyte. While there are other reviews focused on how to design chromophoric ligands for an efficient sensitization of Ln(III) ions, both in the visible and NIR region, this review is application-driven: it is a small collection of particularly interesting examples where the LLB's emissive information is acquired by imaging the emission intensity and/or the fluorescence lifetime (fluorescence lifetime imaging microscopy, FLIM).

X-ray diffraction is ideal for probing the sub-surface state during complex or rapid thermomechanical loading of crystalline materials. However, challenges arise as the size of diffraction volumes increases due to spatial broadening and because of the inability to deconvolute the effects of different lattice deformation mechanisms. Here, we present a novel approach that uses combinations of physics-based modeling and machine learning to deconvolve thermal and mechanical elastic strains for diffraction data analysis.

Circular RNAs (circRNAs), as a class of noncoding RNA molecules with a circular structure exhibit high stability and spatiotemporal-specific expression, making them ideal cancer biomarkers for liquid biopsy. Herein, a new photoelectrochemical (PEC) biosensor for a highly sensitive circRNA assay in the whole blood of lung cancer patients was designed based on CRISPR/Cas13a-programmed Cu nanoclusters (Cu NCs) and a -scheme covalent organic framework/silver sulfide (T-COF/AgS) composite. This -scheme T-COF/AgS composite accelerates electron transfer and produces an excellent initial photocurrent.

Proteins regulate biological functions through the formation of distinct protein complexes. Identification and characterization of these protein-protein interactions are critical to deciphering their mechanism of action. Different antibody-based or cross-linking-based methods have been developed to identify the protein-protein interactions.
