R-C-2921	PAMAM-PLA-EPOX	Polyamide amine dendrimer (PAMAM) is one of the earliest synthesized dendrimers. It is monodisperse, with a cavity inside and a high-density amine group on the surface. As an excellent nano single molecule surfactant, it has good solubilization, demulsification and stability. It has very good practical value in emulsion explosive, oil exploitation, sewage treatment and drug solubilization Ethylene oxide is an important intermediate in organic synthesis, which is used to prepare ethylene glycol, antifreeze, synthetic detergent, emulsifier and plastics.	price>
R-C-2922	PAMAM-PLA-Protected amines(Fmoc, tBOC)	Polyamide amine dendrimer (PAMAM) is one of the earliest synthesized dendrimers. It is monodisperse, with a cavity inside and a high-density amine group on the surface. Dendrimers link PLA and PLA links ammonia.	price>
R-C-2924	PS-b-PBd	Polybutadiene is mainly used as synthetic rubber. Solution polymerized polybutadiene is often used together with styrene butadiene rubber or natural rubber as tread and carcass of tires. Polystyrene resin, English name is poly (styrene), molecular formula is C8H8, general type (R) is suitable for packaging materials; Flame retardant (f) is suitable for building and thermal insulation materials.	price>
R-C-2925	PDPA5K	Block copolymer micelles are usually formed by self-assembly of amphiphilic block copolymers in aqueous media.Hydrophilic and hydrophobic blocks form shell and core micelles,respectively.Methoxypolyethylene glycol(MPEG)-b-Poly(2-diisopropylamino)ethyl methacrylate(PDPA)block copolymer was synthesized by atom transfer radical polymerization of 2-bromoisobutyl bromide and MPEG in the presence of triethylamine catalyst.	price>
R-C-2926	PS-b-P4VP-b-PAA	The formation of block copolymer micelles depends on the attraction of hydrophobic end and the repulsion of hydrophilic end. According to the law of thermodynamics, when the surface free energy of the core-shell interface is smaller, the micelle is more stable. At this time, the micelle shrinks, the interfacial area shrinks, and the spatial repulsion force at the hydrophilic end increases; The interfacial tension and spatial repulsion restrict each other, so that the micelles can not aggregate or relax indefinitely to form a micellar system with stable particle size.	price>
R-C-2928	Bilirubin-Polyethylene glycol-Sialic acid	Sialic acid is a derivative of 9-carbon monosaccharide, a negatively charged ion that can make saliva feel smooth. Polyethylene glycol has good water solubility and good miscibility with many organic components. They have excellent lubricity, moisture retention, dispersibility, adhesives, antistatic agents and softeners	price>

R-C-2950	PAMAM G2-NH2	PAMAM is a polyamide amine dendrimer with colorless to yellowish transparent liquid.As a carrier of drugs,genes and vaccines in the field of biomedicine,it is used for drug sustained-release and targeted release;it is used for in-vitro diagnosis,in vitro gene transfer,gene therapy,nuclear magnetic resonance imaging and other applications.	price>
R-C-2951	PAMAM G3-NH2	PAMAM is a polyamide amine dendrimer with colorless to yellowish transparent liquid.As a carrier of drugs,genes and vaccines in the field of biomedicine,it is used for drug sustained-release and targeted release;it is used for in-vitro diagnosis,in vitro gene transfer,gene therapy,nuclear magnetic resonance imaging and other applications.	price>
R-C-4688	PEI-SH(5%)	Polyethyleneimine is a kind of cationic polymer, which is effective for gene transmission. Polyethyleneimine is non-degradable, and the molecular weight of PEI affects the cytotoxicity and gene transfer activity. Polyimide is a low toxicity and high efficiency gene carrier.	price>
