Summary: A low-cost and environment-friendly sensor was developed using label-free hydrogen doped molybdenum oxide nanoparticles as ratio probes for visual determination of gold ions (Au3+). The reduction of Au3+ to Au nanoparticles (AuNPs) by H0.3MoO3 nanoparticles resulted in a color change of the solution, enabling visual detection of Au3+. The sensor showed satisfactory detection range and limit for Au3+ and can be applied in environmental water samples. Additionally, the resulting AuNPs exhibited stability and oxidase-like activity, making them useful in various fields.

Summary: Researchers have developed an electrical label-free detection method using a remote floating-gate field-effect transistor (RFGFET) with a 2-dimensional reduced graphene oxide (rGO) sensing membrane to detect SARS-CoV-2. The RFGFET sensors showed rapid detection (<5 min), high accuracy (90.6%), and low variation (<6%) when tested with nasal swab samples. The detection limit of the RFGFET sensors for pseudo-SARS-CoV-2 was 10,000 times lower than enzyme-linked immunosorbent assays and comparable to reverse transcription-polymerase chain reaction (RT-PCR) for patient samples. This research has significant implications for rapid SARS-CoV-2 diagnostics.

Summary: Meat adulteration, particularly the addition of low-cost turkey meat mixed with duck and goose meat, poses a serious threat to human health. This study adopts a highly sensitive optical detection technique called SERS (surface enhanced Raman spectroscopy) to target the label-free detection of turkey DNA. Nanomaterial aggregates (Ag, Au, Cu, Al) are fabricated on solid substrates using pulsed laser deposition, and the SERS biosensors are characterized for their structural, morphological, and optical properties. The Au/Si SERS biosensor exhibits enhanced sensing performance and is projected for label-free turkey DNA detection. With high stability, reproducibility, and ultra-sensitivity down to 1.8 fg/uL, this biosensor offers great potential in detecting the major food adulterant of turkey DNA.

Summary: A highly robust crystallization of luminescent metal halide nanocrystals into perfect FCC superlattices on the micrometer scale is achieved using a rapid and direct liquid-phase synthesis. The individual nanocrystals within the superlattice continue to grow and then disassemble into dispersed nanocrystals due to the repulsive interparticle interactions induced by large nanocrystals. The FCC superlattice exhibits a single and slightly redshifted emission, with three times higher quantum yield and improved environmental stability compared to individual nanocrystals.

Summary: A novel PCR-free and label-free DNA sensor based on multiple linear hybridization chain reaction (ML-HCR) and cloth-based closed bipolar electrochemiluminescence was proposed for sensitive and rapid detection of Escherichia coli (E. coli). The sensor showed a linear detection range from 102 to 107 CFU/mL with a low detection limit of 38 CFU/mL. It also demonstrated acceptable selectivity, stability, and reproducibility, and was successfully applied to detect E. coli in milk samples with high recoveries.

Summary: The thermal instability of silver nanowires leads to increased electrical resistance in AgNW networks. Understanding the relationship between structural and electrical properties of AgNW networks is crucial for their integration as transparent electrodes in flexible optoelectronics. In situ X-ray diffraction measurements were used to study the crystallographic evolution of Ag-specific Bragg peaks during thermal ramping, revealing differences in thermal and structural transitions between bare and SnO2-coated AgNW networks.

Summary: Photodynamic therapy (PDT) is a promising local treatment modality in cancer therapy, but its therapeutic efficacy is restricted by ineffective delivery of photosensitizers and tumor hypoxia. In this study, a phototactic Chlorella-based near-infrared (NIR) driven green affording-oxygen microrobot system was developed for enhanced PDT. The system exhibited desirable phototaxis and continuous oxygen generation, leading to the inhibition of tumor growth in mice. This study demonstrates the potential of using a light-driven green affording-oxygen microrobot to enhance photodynamic therapy.
