Summary: In this study, a quadruple UV LED array was designed to directly irradiate gel electrophoresis chips at 275 nm. Simple detection setup using a 365 nm filter, UV camera lens, and CCD was integrated with the small gel electrophoresis chip to construct the IFI-GEC device. The LED array exhibited good evenness and enabled online imaging of the entire gel electrophoresis chip. The reproducible IFI-GEC detection was completed within 10 minutes with a low LOD of 40 ng for lysozyme detection, demonstrating the potential of the IFI-GEC device for stain-free online and portable protein detection.

Summary: The novel AHMT technique provides an automated way to prepare calibration solutions for CE-based quantitative analysis, reducing manual operation and minimizing the risk of errors. Comparison with the standard manual pipetting procedure showed that AHMT results in more consistent calibration curves with significantly reduced volume and potential errors in the obtained solutions. The application of SCIEX(R) nanoVials further enhances the effectiveness of AHMT by decreasing the actual volume of calibration solutions.

Summary: In this study, a multi-input capacitively coupled contactless conductivity detector (MICD)-D-4 was proposed with high sensitivity, and further improved by combining it with differential detection to form (DFMICD)-D-4. The new detector showed improved performance compared to traditional single-input and double-input detectors, with a higher response-to-baseline ratio and a low limit of detection (0.7 nM). It can be applied to the detection of low-conductivity solutions and total dissolved solids (TDS) analysis, demonstrating its versatility and superiority over standard conductivity meters.

Summary: The application of nanosilicon has been found to enhance plant defenses against various stresses. Silicon quantum nanodots, with their unique biological and physiochemical properties, show promise in regulating plant responses to stress. By studying maize, it was observed that the addition of Si NDs and sodium silicate effectively inhibited the growth of caterpillars and activated defense genes. Field experiments also demonstrated the potential of Si NDs in increasing maize yield. These findings suggest that Si NDs can be an effective and ecofriendly crop protection strategy in agroecosystems.

Summary: Cell cycle discrimination is crucial for studying cellular heterogeneity in single-cell analysis based on organic mass spectrometry. A robust protocol using three small molecular indicators was developed to discriminate single cells at different cycle stages in real time. This protocol successfully discriminated single cells at G0/G1, S, and G2/M stages and revealed significant heterogeneity in amino acids, nucleotides, energy metabolic intermediates, and phospholipids among cells at different cycle stages.

Summary: The researchers report an activatable antimicrobial nanoplatform with ultralow-background persistent luminescent (PL) turn-on imaging and therapeutic capability. The platform utilizes chitosan as a linker to immobilize copper ions on the surface of persistent luminescent nanoparticles (PLNPs) to fabricate PLNPs-CS-Cu2+. The PL emission of PLNPs is quenched by Cu2+ under physiological conditions but recovered due to the conversion of Cu2+ into Cu+ by high glutathione (GSH) levels at the infection site. The as-prepared antibacterial nanoplatform shows promise for highly sensitive persistent luminescent imaging and simultaneous treatment of bacterial infection.

Summary: Inspired by the nanotopography of cicada wings, a highly sensitive tactile sensor was fabricated by nanotexturing polyaniline nanoneedles on a conductive and elastic carbon skeleton. The sensor exhibited ultrahigh sensitivity, fast response/recovery abilities, and reproducible sensing performance, making it capable of distinguishing motions in a wide pressure range, detecting spatial pressure distribution, and monitoring various gestures in a wireless manner. These excellent performances demonstrate the great potential of nature-inspired tactile sensors for practical human motion monitoring and artificial intelligence applications.

Summary: A pH-responsive colorimetric microneedle (MN) patch made from bromothymol blue (BTB) and silk fibroin meth acryloyl (SilMA) was developed for sensing salmon spoilage. The MN patch could extract tissue fluids from salmon and display color changes based on the pH variation caused by the increase of total volatile basic nitrogen. This method allows rapid determination of salmon spoilage and can be analyzed nondestructively on a smartphone.

The LOI of the PHA/HBM-B composite reached 27.6% when the mass ratio of HBM to BNT was 75/25. When the content of HBM-B reached 15 wt%, the LOI of PHA-Based composites reached 29.6% and achieved a UL-94 rating of V-0, meeting the standard of flame-retardant material.

Summary: Ball milling is effective in activating and reducing the size of microscale zero valent iron (mZVI) and sulfidating mZVI mechanochemically. However, there are differences in the interaction between chlorinated ethenes (CEs) and ball milled mZVI (mZVIbm) and mechanochemically sulfidated mZVI (S-mZVIbm) that are not well understood. This study found that simple ball milling exposed active Fe0 sites, while mechanochemical sulfidation decreased Fe0 sites and increased S2 sites. The sulfidation process enhanced the reactivity of TCE dechlorination the most, followed by PCE and 1,1-DCE, but reduced the reactivity of trans-DCE, cis-DCE, and VC compared to simple ball milling. Sulfidation also improved the electron efficiency of CE dechlorination, except for cis-DCE and VC. The kSA of cis-DCE, VC, and trans-DCE dechlorination positively correlated with the sulfide content.

Summary: This study developed a pH-responsive theragnostic nanoplatform for targeted imaging and local drug release at the bacterial infection site. The nanoplatform consists of core-shell structure with persistent luminescence nanoparticles (PLNPs) as the core and zeolitic imidazolate framework-8 (ZIF-8) as the shell loaded with antibiotics. The nanoparticles were further conjugated with folic acid (FA) to achieve autofluorescence-free targeted imaging at the infection site. The acidic microenvironment at the bacterial infection site enables ZIF-8 to decompose and release drugs, improving the efficacy of bacterial infection treatment.

Summary: Coating mesoporous drug carriers on the surface of persistent luminescence nanoparticles (PLNPs) enables continuous luminous imaging and drug release guidance. However, this encapsulation often reduces the luminescence of PLNPs, and conventional drug-loaded shells have difficulties in achieving responsive fast drug release. In this study, mesoporous polyacrylic acid (PAA)/calcium phosphate (CaP) shell-coated PLNPs (PLNPs@PAA/CaP) were fabricated to improve afterglow bioimaging and drug delivery. The PAA/CaP shell effectively prolongs the luminescence of PLNPs and enables efficient drug delivery. Under acidic conditions, PAA/CaP shells degrade and release drugs rapidly for effective bacterial killing. The prepared PLNPs@PAA/CaP show great potential for diagnostic and therapeutic applications.
