Summary: Singlet oxygen (1O2) plays an important role in chemistry, medicine, and human physiology, but its use in biological systems is limited due to a lack of efficient probes. This review discusses the current developments of probes and molecular carriers of 1O2, which typically consist of a 1O2-specific binding unit and a signaling unit. Based on the signaling mode, these probes can be categorized into absorption-based, colorimetric, photoluminescent, and chemiluminescent. The review also highlights the factors affecting their efficiency and identifies unexplored areas for potential future developments.

Summary: A novel light-harvesting platform is designed by decorating photosensitizer Ce6 into an inverse opal photonic hydrogel framework to enhance the efficiency of photodynamic antibacterial therapy. It is shown that the relative positions of the photonic bandgap of the hydrogel and the absorption band of Ce6 can tune the generation efficiency of singlet oxygen. The slow photons at the blue edge of the photonic bandgap exhibit advantages in improving singlet oxygen generation compared to those at the red edge.

Summary: The study focused on the impact of aPDT with curcumin and silver nanoparticles as photosensitizers on planktonic and biofilm forms of Pseudomonas aeruginosa. The results indicated that the combination of curcumin and AgNPs in aPDT reduced the number of bacteria and did not show significant photocytotoxic effects on human normal fibroblast cells, while decreasing glutathione peroxidase (GPx) activity. The ROS production in curcumin plus AgNPs aPDT was higher than the control group, suggesting potential novel strategies in treating multi-drug-resistant bacteria like P. aeruginosa.

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.
