Depression is linked to dysregulated neurotransmitter levels, making efficient and facile monitoring crucial for early diagnosis and improved treatment outcomes. However, rigid electrodes or unstable luminescence on flexible substrates have limited the adoption of electrochemiluminescence (ECL) in flexible health-monitoring platforms. Herein, we introduce a stretchable conductive photonic-crystal hydrogel (PCH) as an ECL electrode for sweat-based neurotransmitter detection.

Serine serves as a metabolic nexus in tumors, coordinating one-carbon metabolism, nucleotide synthesis, and redox regulation. While serine transporters (SerTs) are known to be dysregulated in cancer, their functional nanoscale organization remains unresolved due to the limitation of resolution imaging and available probes. Here, we developed a substrate-based fluorescent probe (Ser-probe) enabling direct stochastic optical reconstruction microscopy of SerTs, revealing malignancy-associated clustering assembly of SerTs that correlates with transport capacity.

The asialoglycoprotein receptor (ASGPR) is a promising therapeutic target for drug delivery systems in hepatocellular carcinoma (HCC), exhibiting high affinity for specific carbohydrate residues and overexpression on malignant hepatic cells. However, their functional mechanisms remain poorly resolved at the single molecule level, hindering the rational optimization of ASGPR-targeted drug delivery systems. Here, we developed a trivalent -acetylgalactosamine (TriGalNAc)-functionalized ligand probe leveraging high affinity to enable the nanoscale visualization of ASGPR organization and trafficking via super-resolution imaging.

As a successor to the DArk Matter Particle Explorer (DAMPE), the Very Large Area γ-rays Space Telescope (VLAST) is being designed to strengthen γ-ray observations and extend the cosmic ray nuclei measurements up to Zr (Z = 40) and even heavier ions. Consequently, a large dynamic range is required by the charge detector of VLAST to cover the measurements of cosmic ray particles from the proton to ultra-heavy ions. To achieve the requirements, a readout design based on the three dynodes signal extracted from the photomultiplier tube has been proposed.

As one of the factors regulating tumour angiogenesis, angiopoietin-4 (ANGPT4), which plays an important role in promoting tumour proliferation, survival, expansion and angiogenesis, is highly expressed in some tumours, such as lung adenocarcinoma, glioblastoma and ovarian cancer. This may be related to the fact that ANGPT4 affects the blood vessels and lymphatic system of the tumour. Specifically, ANGPT4 could play an effective role in promoting cancer by affecting the tyrosine kinase receptor TIE2, ERK1/2 and PI3K/AKT signalling pathways.
