Aminated magnetic microspheres
0 ImagesCat. No.: HY-184641Aminated 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.

Monodisperse Fe3O4 microspheres
0 ImagesCat. No.: HY-184635Monodisperse Fe3O4 microspheres (Monodisperse iron oxide microspheres) are microspheres composed of magnetic materials, with iron oxide as the main component. These microspheres are very uniform in size and exhibit monodispersity, meaning that the sizes of the microspheres are very similar with minimal differences.

PEG2000 Fe3O4 Methoxy group end
0 ImagesCat. No.: HY-184623PEGylated iron oxide nanoparticles (methoxy-terminated) are prepared by high-temperature pyrolysis and modified with PEG-methoxy-terminated oleic acid-modified iron oxide. This modification transforms the nanoparticles from the oil phase to the aqueous phase, thereby broadening their application in the biological field.

Reactive oxygen responsive hydrogel
0 ImagesCat. No.: HY-184600Reactive oxygen species responsive hydrogels are a novel class of smart hydrogels, formed by the cross-linking of ROS-responsive modules through covalent, coordination, or supramolecular interactions. Due to the introduction of these ROS-responsive modules, these hydrogels exhibit a sensitive response to the oxidative stress microenvironment present in organisms. PVA-TSPBA hydrogel is a hydrogel formed by the cross-linking polymerization of polyvinyl alcohol (PVA) and the reactive oxygen species-sensitive cross-linking agent N1-(4-benzyl borate)-N3-(4-phenyl borate)N1,N1,N3,N3-tetramethyl-1,3-propanediamine (TSPBA). This hydrogel consists of two parts: a boric acid precursor (TSPBA) and an aqueous solution of PVA. The boric acid bonds on TSPBA and the hydroxyl groups on PVA rapidly cross-link to form borate ester bonds, thus forming the hydrogel.

Hollow mesoporous polydopamine nanoparticles
0 ImagesCat. No.: HY-184614Mesoporous polydopamine nanoparticles are mesoporous nanomaterials formed by the self-polymerization of dopamine hydrochloride under alkaline conditions. Their main component is the dopamine polymer, a biomacromolecule exhibiting good adhesion and reducing properties, demonstrating excellent biocompatibility and bio-interaction capabilities.
