Summary: A new two-photon fluorescent viscosity rotor combining an electron-rich unit with an electron-deficient fluorophore was developed for ratiometric two-photon fluorescent detection of intracellular viscosity. The rotor showed sensitive fluorescence responses to changes in viscosity in a methanol/glycerol system, and also displayed good cell imaging performance and targeting ability in living cells.

Summary: The liver, as the metabolic and detoxification center, plays a vital role in various physiological processes. Normal liver function is crucial for maintaining overall health, while abnormal liver function can lead to liver diseases. Early diagnosis of liver diseases is essential for timely treatment. The use of fluorescent probes for detecting biomarkers of liver diseases has provided valuable insights for pathological studies, drug development, and disease diagnosis and treatment in recent years. This review summarizes the progress of fluorescence probes in detecting hepatopathy-related biomarkers and discusses the current challenges and future directions. The development of long wavelength probes, multi-detection probes, quantitative analysis probes, and multi-modal probes is expected to be a popular trend. This review aims to facilitate the development of novel fluorescent probes for disease detection and provide guidance for diagnosis and treatment.

Summary: Carbon nanohorns were non-covalently functionalized with two different benzothiadiazoloquinoxalines via Stille cross-coupling reactions and solvent-free microwave irradiation. The organic molecules and nanostructures exhibited close interactions, leading to significant Raman enhancement and making them appealing for various applications. Both experimental physico-chemical characterization and in silico studies were conducted to gain insights into these phenomena. The processability of the hybrids allowed for the preparation of homogeneous films on diverse substrates.

Summary: This study presents a new phase-changing perfluorocarbon nanodroplet contrast agent that improves sensitivity of fluorescence imaging by externally modulating the signal. The nanodroplets undergo liquid-to-gas phase transition when exposed to an externally applied laser pulse, increasing the fluorescent signal. It also demonstrates the production of ultrasound contrast for multimodal imaging.

Summary: This study reports the development of a series of ratiometric optical force probes (OFPs) based on fluorescent-protein-dye and protein-protein conjugates, and their incorporation into genetically engineered bio-glues. The OFPs efficiently modulate Forster resonance energy transfer upon force application, reporting on force-induced molecular alterations independent of concentration and fluorescence intensity. By fluorescence spectroscopy in solution and in the solid state, as well as fluorescence lifetime imaging microscopy, stress concentrations are visualized and adhesive and cohesive failure in the fracture zone is differentiated.

Summary: Zinc is a crucial metal element with wide applications in various fields, and its deficiency can lead to multiple diseases. Selective recognition and effective detection of free zinc ions are highly important. Fluorescent probes, with their high sensitivity, selectivity, real-time monitoring capability, and ease of operation, have been widely used for metal ion detection, including convenient and low-cost methods for Zn2+ detection. This article reviews the latest research advances in fluorescent chemosensors for Zn2+ detection from 2019 to 2023, discussing various mechanisms such as PET, ESIPT, ICT, FRET, CHEF, and AIE. The use of these mechanisms in detecting zinc ions is explored through specific cases, some of which have been validated through theoretical calculations.

Summary: A dual-locked and tandem activatable probe (DTAP) is developed for real-time NIRF imaging of intratumoral pyroptosis during cancer chemo-immunotherapy in living mice. The activated signal of DTAP correlates well with tumor-infiltrating cytotoxic T lymphocytes and tumor growth inhibition, enabling the prediction of cancer therapeutic efficacy. This study provides a non-invasive technique to study the regulatory mechanism of pyroptosis in cancer therapy and optimize cancer chemo-immunotherapies.

Summary: Recent research focuses on the development of redox probes for in vivo applications, particularly near-infrared fluorescent sensors and tricyanofuran-based fluorophores. The tricyanofuran-based boronate probe forms an adduct with glutathione, decreasing its reactivity towards oxidants, while a modified probe derived from 1-naphthalene boronic acid reacts similarly with peroxynitrite but is not influenced by glutathione, making it suitable for real-time monitoring of peroxynitrite formation.
