Summary: In this study, a long-wavelength mitochondria-targeted fluorescence turn on probe TL was developed for the detection of ONOO-. TL exhibited excellent characteristics, including fast response time, high sensitivity, and specific emission wavelength. It also demonstrated good mitochondria targeting and visualization of both exogenous and endogenous ONOO- in biological systems. Furthermore, TL was used to monitor the up-regulation of ONOO- induced by high concentration of dexamethasone, suggesting its potential for studying the fluctuation of ONOO- in physiological and pathological systems.

Summary: DNAzymes hold great promise as transducing agents for the analysis of intracellular biomarkers. However, their low delivery efficiency and limited signal amplification capability hinder their application in low-abundance biomarker analysis. In this study, a general strategy to design an intelligent, autocatalytic DNAzyme biocircuit is developed for amplified microRNA imaging in living cells. The DNAzyme biocircuit is constructed based on a nanodevice composed of catalytic hairpin assembly (CHA) and DNAzyme biocatalytic functional units, sustained by Au nanoparticles (AuNPs) and MnO2 nanosheets (CD/AM nanodevices). The intelligent autocatalytic multilayer DNAzyme biocircuit can effectively avoid signal leakage and obtain high amplification gain, expanding the application of programmable complex DNA nanocircuits in biosensing, nanomaterial assembly, and biomedicine.

Summary: The study found that two bis(styryl) dyes have strong affinity for DNA and RNA, with their binding mode shifting between DNA groove binding and RNA intercalation. The fluorescence enhancement effect is more pronounced on DNA than on RNA, and the presence of energy transfer in the bis(styryl) system increases the Stokes shift of the dye.

Summary: Two viscosity-sensitive fluorescent probes were designed and synthesized to localize in lysosome and mitochondria in living HeLa cells, respectively. The fluorescence quantum yield and two-photon absorption cross section of the probes were significantly increased with the increase of viscosity. Fluorescence lifetime imaging of the cells stained with the probes revealed the viscosity range of lysosome and mitochondria. This type of probe is of great importance for monitoring diseases associated with abnormal viscosity.

Summary: Strategies for tumor-specific molecular imaging based on signal amplification have potential in evaluating tumor metastasis and progression. However, traditional amplification strategies are limited by off-tumor signal leakage. In this study, an enzyme-activated autonomous-motion DNAzyme signal amplification strategy (E-DNAzyme) was designed for improved spatial specificity in tumor-specific molecular imaging, which can be specifically activated by overexpressed APE1 in tumor cells. The proposed E-DNAzyme showed a lower detection limit and a higher discrimination ratio compared to traditional amplification strategies.

Summary: There is a pressing need for the development of highly sensitive and selective fluorescence probes for ONOO- in mitochondria. In this study, we introduced a ratiometric fluorescent probe COUS, which utilized a coumarin-cyanine hybrid as the fluorophore and C = C bonds as reaction sites of ONOO-. The probe COUS displayed sensitivity and selectivity towards ONOO-, with a large fluorescence emission shift (239 nm) and a low detection limit (41.88 nM). Furthermore, COUS demonstrated mitochondrial targeting ability, and the targeting moiety could dissociate from the probe upon reaction with ONOO-, enabling accurate detection of ONOO- in mitochondria.

Summary: In order to detect the level of thiophenols in the environment and biological samples, probes 1a-b were synthesized by introducing the 2,4-dinitrophenyl ether group into diethylcoumarin-salicylaldehyde based compounds. These probes can form host-guest compounds with methylated beta-cyclodextrin, showing significant increase in fluorescence intensity in thiophenols detection. The hydrophobic cavity of methylated beta-cyclodextrin enhances the fluorescence intensity of probes 1a-b and reduces their detection limits to thiophenols, without affecting their selectivity and response time.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
