Summary: In this study, a new design of Forster resonance energy transfer-based dual-color photoswitchable fluorescent nanoparticles (DPF NPs) was reported by using ligand-protected gold nanoclusters (AuNCs). The ultrasmall-sized AuNCs act as the FRET donors and also regulate the properties of spiropyran through ligand-spiropyran interactions. These DPF NPs exhibit high fluorescence on/off ratios for both green and red fluorescence emission, and show good reversibility during cycled photo-stimulation. Cell imaging experiments demonstrated that DPF NPs can specifically accumulate in lipid droplets and enable photoswitchable dual-color imaging in living cells.

Summary: A thorough understanding of antimicrobial mechanism is crucial for developing novel antibacterial agents. In this study, cationic bovine serum albumin-protected AuAgNCs were synthesized and their antimicrobial process was investigated in real-time using fluorescence imaging. The cBSA-AuAgNCs exerted their antimicrobial effects by attaching on the outer membrane of bacteria without obvious internalization. Mechanistically, the cationic NCs caused disruption to the bacterial membrane due to strong electrostatic interactions, leading to the accumulation of reactive oxygen species (ROS) and eventually bactericidal action.

Summary: In recent years, there has been great interest in the development of organic near-infrared (NIR) ratiometric fluorescent probes. Traditional intensity-based probes lack an internal standard method, resulting in unreliable and inaccurate detection signals as well as an inability to achieve quantitative determination of analytes. Smart dual emission probes with built-in correction ability have overcome the limitations of single channel fluorescent probes and enable reliable quantitative image analysis. Moreover, fluorescent chemosensors in the NIR window offer advantages such as high signal-to-noise ratio, low tissue damage, and deep tissue penetration. The combination of the advantages of ratiometric fluorescent probes and single-intensity-based NIR probes in NIR ratiometric fluorescent probes has led to their widespread application in biomedical research and clinical practice. This review provides a systematic summary of the recent advances (2020-2022) in this field, discussing the design strategies, sensing mechanisms, and bioapplications of these intelligent fluorescent probes. The challenges and prospects in this promising field are also addressed, with the anticipation that this work will inspire the development of organic NIR ratiometric fluorescent probes.

Summary: A novel dual-emissive fluorescence nanoplatform was designed for ATP sensing based on red emissive europium metal-organic framework (Eu-MOF) and blue emissive gold nanoclusters (AuNCs). The presence of ATP caused the decomposition of Eu-MOF, resulting in a decrease in red emission while the blue emission of AuNCs remained unchanged. This emission intensity change enabled the establishment of a ratiometric fluorescent and visual sensor of ATP. A fluorescent paper-based sensor was also fabricated for easy-to-use and visual detection of ATP in serum samples using a smartphone.

Summary: A novel type of MOF nanocomposite with gold nanorods (AuNRs) and gold nanoclusters (AuNCs) was designed to achieve remarkable visible light photocatalytic antibacterial activity. The introduction of AuNRs improved the visible light absorption of ZIF-8, enhancing the production of reactive oxygen species (ROS). Additionally, AuNCs were integrated into the composites to further generate ROS under visible light irradiation. The obtained nanocomposites exhibited strong photo-bactericidal activity against Escherichia coli and Staphylococcus aureus, and could be easily deposited on mask fibers for excellent antibacterial properties compared to commercial masks. This study provides a new plasmon-enhanced approach for enhanced photo-bactericidal activity of MOFs in environmental and biomedical fields.

Summary: Ultrasmall gold nanoclusters (AuNCs) with distinct photoluminescence properties were effectively modulated by encapsulating them into zeolite imidazolate frameworks-8 (ZIF-8), resulting in enhanced near-infrared (NIR) fluorescence intensity. The AuNCs@ZIF-8 composites exhibited an emission maximum at 830 nm, longer than AuNCs without ZIF-8 encapsulation. This strategy was utilized for the detection of acetylcholinesterase (AChE) using a ratiometric fluorescent sensing platform, showing high sensitivity and good specificity in biological samples.

Summary: By functionalizing MoS2 quantum dots (QDs) with l-/d-penicillamine, we found that d-MoS2 QDs exhibited a positive effect in promoting the growth, proliferation, and migration of human umbilical vein endothelial cells. This distinct phenomenon was largely attributed to the higher internalization efficiency of d-MoS2 QDs than l-MoS2 QDs and chirality-dependent nano-bio interactions. In vivo angiogenic assay demonstrated that the expression level of angiogenic markers in newly-formed skin tissues of the d-MoS2 QDs group was higher than that in the l-MoS2 QDs group, leading to accelerated re-epithelialization and improved skin regeneration.
