Gold nanorods are rod-shaped nanoparticles made of gold, with dimensions ranging from a few nanometers to hundreds of nanometers. These nanoparticles have unique and rich physical and chemical properties, such as high surface electric field intensity enhancement and tunable photothermal conversion efficiency. These properties make gold nanorods ideal for applications...

Studying the spatial distribution of proteomes in cells is crucial for understanding various molecular mechanisms in cell biology. In recent years, proximity chemical labeling technology, especially APEX (Engineered Ascorbate Peroxidase), has rapidly advanced. This method enables proximity labeling of proteins and RNA in specific spatial regions within living cells, avoiding...

High-fidelity in vivo fluorescence monitoring of physiological processes is crucial in disease diagnosis and biological research, but it faces extreme challenges due to aggregation-induced quenching (ACQ) and short-wavelength fluorescence. The development of high-performance, long-wavelength aggregation-induced emission (AIE) fluorophores has placed higher demands on precise optical bioimaging.Chromophore-quinoline-malononitrile (quinolinenitrile, QM) is a...

FM series fluorescent dyes include FM 1-43, FM 2-10, FM 5-95, and FM 4-64. They are a type of lipophilic styrene fluorescent dyes that are non-toxic to cells and are mainly used for living cell membranes, especially plant samples. Specific labeling of cell membranes, tracer imaging of neuronal cells, and...

Conventional methods for attaching single-stranded DNA (ssDNA) to IgG antibodies often face several challenges. These include high costs associated with ssDNA modification, low coupling efficiency, complex reaction and purification processes, and difficulties in controlling the stoichiometry between ssDNA and IgG.  Professor Hang Xing from Hunan University developed the "AND Linker”,...

-- J&K Scientific exclusively offers two monomers developed by Prof. Yin. The fossil resources derived 4,4’-biphenyldicarboxylic acid is a significant monomer in polymer industry [1]. However, its production route is lengthy and dirty with low selectivity, and the corresponding polymers are also poorly biodegradable. In view of increasing concerns about...
