Summary: This study investigated the adsorption, elimination, and toxicity of silver nanoparticles and silver nitrate in biofilms composed of the model bacterium Escherichia coli and natural mixed-species. The results showed that natural mixed-species biofilms were more tolerant to silver nanoparticles and silver ions than E. coli biofilms, and silver ions were more toxic to both biofilms than silver nanoparticles. The concentrations of certain biomolecules and metabolic enzymes were also found to be significantly different in the two types of biofilms, highlighting the advantages of metal-exposed natural mixed-species biofilms in terms of both structure and metabolic function. These findings contribute to our understanding of the environmental risks of engineered nanoparticles and provide insights into biofilm-based remediation of nanoparticles-contaminated aquatic environments.

Summary: Amino acids are essential for metabolism but can be toxic at high levels intracellularly. Downregulation of amino acid transporters in Saccharomyces cerevisiae is a mechanism to avoid toxicity. Overexpression of certain amino acid transporters can induce growth defects, and various amino acids are growth inhibitory to yeast cells when transported into the cell at high levels.

Summary: This work describes the synthesis of sebacic acid capped silver nanoparticles (SA-AgNPs) for detecting L-Histidine in biological samples. The nanoparticles were characterized to be stable spherical particles with a diameter of 11 nm, showing surface plasmon resonance at 420 nm. The addition of L-Histidine induced aggregation of SA-AgNPs, resulting in a color change and reduced SPR band absorbance for detection with a low limit of 122 nM.

Summary: A yellow emitting long afterglow luminescence material SrSc2O4:Pr3+ was successfully prepared. It exhibits multiple long afterglow luminescence peaks corresponding to Pr3+ f-f transitions, with the afterglow emission falling in the yellow region. The optimal sample doped with 1 at% Pr3+ shows an afterglow luminescence persisting for over 3 hours. Thermoluminescence results indicate the formation of three traps caused by the addition of Pr3+ ions, with the trap density reaching its maximum at 1 at% Pr3+ doping, resulting in the longest afterglow luminescence.

Summary: In this paper, sensitive mechanoluminescence phosphors Sr3Al2O5Cl2:Eu2+, Tm3+ were developed and the effect of co-doped Tm3+ ions on ML properties was investigated. The results showed that the ML emission originated from Eu2+ emitting center and the density of shallow traps increased greatly with the increase of co-doped Tm3+ ions, resulting in strong sensitive ML intensity. Additionally, deep traps could provide long time stable ML emission under strong compressive load. These findings indicate the great potential of Sr3Al2O5Cl2:Eu2+, Tm3+ phosphors in the detection of weak stress and long time stable ML.

Summary: In this study, X-ray induced color-tunable long afterglow luminescent material Ca9-xTb(PO4)7:xMn2+ was synthesized and the effects of Mn2+ doping concentration on the properties of the samples were investigated. Efficient energy transfer between Tb3+ and Mn2+ under X-ray excitation was observed, contributing to tunable green-red emission. Increasing Mn2+ concentration led to a decrease in green afterglow emissions of Tb3+ and an increase in red afterglow emissions of Mn2+, resulting in enhanced long afterglow luminescence properties.

Summary: We have developed a novel strategy to design efficient X-ray-induced long afterglow luminescent materials. By using Eu3+ ions as trap creators and emitting centers, and scintillator Bi4Ge3O12 as the host to absorb X-ray efficiently, we obtained excellent X-ray induced red long afterglow luminescence from Bi4Ge3O12:Eu3+ material. The luminescence persisted for more than 5400 s and could still be observed by naked eyes. This strategy provides a pathway for the development of high-performance X-ray induced long afterglow phosphors.
