Antibody-drug conjugates (ADCs) are conjugated products of monoclonal antibodies (mAbs) and cytotoxic small molecules. In tumor treatment, although monoclonal antibodies have good targeting properties, most of them target extracellular or cell surface antigens, have weak anti-tumor activity, have limited therapeutic effect on solid tumors, and are more likely to develop drug resistance; conventional anti-tumor chemotherapy Although drugs have high anti-tumor cell activity, they lack targeting an...

What are Dyed Polystyrene Latex Particles? Polystyrene particles (PSP) are commercially available in different sizes, ranging from 15 nanometers to several micrometers, with narrow size distributions and various surface chemistries. Additionally, polystyrene is generally considered inert and nontoxic, making it safe for use in a variety of biological assays. Dyed polystyrene latex particles or colored latex beads have excellent multiplexing capability and have the following characteristics: a...

As a promising systemic drug delivery method, transdermal drug delivery system (TDDS) is easier and more convenient to operate than traditional oral, intravenous and subcutaneous injection methods. It can improve patient compliance while also avoiding First-pass effect and drug side effects. As the largest organ of the human body, the skin is also the body’s first line of defense against foreign microorganisms and chemical substances. Its drug permeability is lower, which is orders of magnitude ...

Hydrogel is a three-dimensional network of hydrophilic polymers that swells in water without dissolving. Because the polymer contains a large number of hydrophilic groups, the hydrogel can absorb and lock a large amount of water. After absorbing water, the hydrogel network can maintain its original shape without being destroyed. Hydrogels are widely used in tissue engineering, drug delivery, biosensing, etc. due to their simple preparation, strong tunability of mechanical properties, good biocom...

Surface plasmon resonance (SPR) and surface-enhanced Raman scattering (SERS) are two key surface plasmon technologies that ultimately enable single-molecule-level chemical and biological sensors. Due to the tremendous progress in solution-based synthesis methods, plasmonic nanoparticles with various complex shapes (e.g., spheres, rods, and prisms) have been widely used for surface plasmon resonance and surface-enhanced Raman scattering sensing. Localized surface plasmon resonance (LSPR) around p...

Micelles refer to molecularly ordered aggregates that begin to form in large quantities after the surfactant concentration reaches a certain value in an aqueous solution. In micelles, the hydrophobic groups of surfactant molecules aggregate to form the core of the micelle, and the hydrophilic polar groups form the outer layer of the micelle. Liposomes are an artificial membrane. In the water, the hydrophilic head of the phospholipid molecule is inserted into the water, and the hydrophobic tail o...
