R-C-406	PASP-PEG-PASP	Polyaspartic acid polyethylene glycol polyaspartic acid pasp-peg-pasp is one of the most commonly used biodegradable functional polymers and polypeptide amino acid copolymers.It can be used for passive targeting,active targeting and drug delivery of micelles and vesicles.The side group free COOH on poly (L-Aspartic acid)-peg poly(L-Aspartic acid)(PASP peg PASP),P(L-Asp)can be used to modify the micelle core.	price>
R-C-793	G0-C14 CAS:1510653-27-6	G0-C14 is a cationic lipid-like compound alkyl-modified polyamidoamine (PAMAM) dendrimer.The particles are composed of three parts:outer peg surface,PLGA/G0-C14 layer,which play two roles:as a polymer matrix loaded with non-polar drugs,protecting and promoting siRNA molecules to stay in NP core and control drug release,and an aqueous inner core containing siRNA.	price>
R-C-927	poly(β-amino esters) Encapsulated DNA	The main synthesis method of PBAE is Michael addition reaction.The results showed that PBAE with different end groups had different gene transfection efficiency,and the hydrophilic amino group containing hydroxyl or extra amine had the best transfection efficiency;the amino group in the polymer was protonated under acidic conditions,and could bind to the drug or DNA containing negative ions,so that it could be effectively encapsulated.Because there were only tertiary amines in the straight chain PBAE,and there might be primary and secondary amines in the branched chain PBAE,When DNA nanoparticles were formed, the encapsulation ability of branched chain PBAE was stronger than that of straight chain PBAE,and the diameter of branched chain amino ester nanoparticles was smaller.	price>
R-C-929	FA-hyaluronic acid-PAE（PAE20% FA7%）	Hyaluronic acid is a biochemical drug with high clinical value,which is widely used in cosmetics.It can play a unique role in protecting the skin.It can keep the skin moist,smooth,delicate,tender and elastic.It has the functions of anti wrinkle,anti wrinkle,beauty care and recovery of skin physiological function.	price>
