Benzil is a 1,2-diketone compound with multiple functions including photo-peroxidation initiator, crosslinking initiator and pattern-forming agent, and is commonly used as a precursor for photodegradable network crosslinkers. In oxygen-purged polymer films or glassy matrices, Benzil reacts with molecular oxygen under illumination at wavelengths greater than 370 nm or 400 nm, and converts to benzoyl peroxide in nearly quantitative yield. Subsequently, the generated benzoyl peroxide groups produce free radicals via thermal or photochemical decomposition, thereby enabling crosslinking of polymer chains, grafting of new monomers, and preparation of patterned polymers on solid surfaces using mask irradiation. Benzil also induces crosslinking of photodegradable poly (phenyl vinyl ketone) to form a stable photodegradable polymer network .

Aminated magnetic microspheres are superparamagnetic magnetic particles with amino functional groups modified on their surface, widely used in biomedical and molecular biology research. This 1μm aminated magnetic microsphere is composed of polystyrene and nano-iron oxide, exhibiting hydrophilicity and good biocompatibility. The aminated magnetic microspheres possess superparamagnetism, fast magnetic response, good monodispersity, ensuring reaction uniformity and detection consistency. The unique rough surface structure and polymer modification give the aminated magnetic microspheres a high amino density, allowing them to covalently couple with bioligands such as peptides, proteins, oligonucleotides, drug molecules, and glycoproteins through the action of special chemical reagents (such as glutaraldehyde). They serve as excellent coating materials and are important carrier tools in medical and biomolecular research.
Cat. No.: HY-184625
Polyethyleneimine (PEI)-modified magnetic iron(III) oxide (Fe3O4) nanoparticles are a composite nanomaterial that combines the properties of magnetic nanoparticles and polyethyleneimine. Polyethyleneimine is a highly branched polymer with a high density of amino groups. These amino groups stabilize the Fe3O4 nanoparticles and provide sites for further functionalization. The amino groups of PEI impart a high surface positive charge to the Fe3O4 nanoparticles, which helps enhance their interaction with negatively charged cell membranes.
Cat. No.: HY-K3120
MCE Serum/Plasma Exosome Isolation and Purification Kit (Magnetic Beads) utilizes a magnetic bead-based method for the isolation and purification of exosomes. The underlying principle is based on the charge-dependent interaction between exosomes and functional polymers on the surface of the magnetic beads under an optimized buffer system, enabling selective adsorption of exosomes. Subsequent adjustment of the ionic strength and pH of the buffer promotes the gentle dissociation of exosomes from the magnetic beads, thereby enabling efficient exosome isolation and purification while maintaining high vesicle integrity and low impurity carryover.

N-Benzylacrylamide (Benzyl acrylamide) is a hydrophobic monomer. N-Benzylacrylamide can form hydrophobic microdomains that act as physical cross-linking sites to connect polymer chains to each other into a three-dimensional network; dynamically reversible hydrophobic interactions enable the spontaneous reformation of physical cross-linking sites after contact of fractured surfaces, thereby achieving autonomous self-healing. N-Benzylacrylamide can promote the synthesis of carboxymethyl cellulose-modified amphiphilic copolymers, and enhance the intermolecular association, viscoelasticity, thermal stability, as well as fire resistance/fire extinguishing performance of the resulting hydrogels .
Cat. No.: HY-P5552A
Melimine acetate is an antimicrobial peptide with broad-spectrum antimicrobial activity against Gram-negative/Gram-positive bacteria, fungi and protozoa. Melimine acetate neutralizes endotoxin activity by interacting with the phosphate groups of lipid A, depolarizes and permeabilizes the cytoplasmic membrane of *Pseudomonas aeruginosa*, and induces bacterial lysis. Melimine acetate exerts additive antiviral effects against H1N1 and MHV-1 when used in combination with RK610. Melimine acetate retains its antimicrobial activity when conjugated to polymer and titanium surfaces. Melimine acetate can be used in infection-related research .
Cat. No.: HY-184644
PEGylated magnetic manganese-zinc ferrite nanocrystals (methoxy-terminated) are made by modifying manganese-zinc ferrite with PEG methoxy groups. PEG is a polymer with good water solubility and biocompatibility. By coating the surface of magnetic nanocrystals with PEG molecules, their water solubility, stability, and biocompatibility can be improved. PEGylation can also reduce non-specific interactions between nanocrystals and organisms, reduce toxicity, and prolong their circulation time in vivo. Furthermore, PEGylated magnetic manganese-zinc ferrite nanocrystals can be further functionalized, such as by attaching targeting groups or drug molecules, to achieve more precise diagnosis and treatment.

Carboxylated magnetic microspheres (low nonspecificity) are functionalized nano- or micron-sized magnetic particles with abundant carboxyl functional groups on their surface. Special chemical treatments reduce the likelihood of nonspecific adsorption. This 1μm carboxylated magnetic microsphere features a core-shell structure: a PS core, an outer layer of iron oxide (Fe3O4), and an outermost encapsulation layer. The carboxyl groups are obtained through polymer modification. Exhibiting low nonspecific adsorption, these microspheres can covalently couple with bioligands such as peptides, proteins, antibodies, and oligonucleotides using specific chemical reagents (e.g., EDC), making them particularly suitable for cell sorting, affinity chromatography, and immunoassay.

5β-Cholanic acid is a hydrophobic modifier used to modify polymer carriers. 5β-Cholanic acid can improve the acid stability, cell penetration efficiency and drug sustained release ability of nanocarriers, and optimize the oral effectiveness of delivered molecules. 5β-Cholanic acid can covalently bind to Glycol chitosan (GC) to form a GC-CA conjugate, which optimizes the hydrophobic anchoring ability of nanoparticles and enables them to be stably adsorbed on the surface of PLGA nanoparticles. Such nanoparticles can resist dissociation in the gastric acid environment and maintain positive charge to enhance endocytic uptake by intestinal epithelial cells (such as Caco-2 cells). 5β-Cholanic acid can be used in the development of drug delivery systems .
