POLYAMINO ACID
Poly‑L‑Glutamic Acid (PLGA )
High‑purity anionic polyamino acid by NCA polymerization, narrow PDI, fully biodegradable. Ideal for dermal fillers, hydrogel crosslinking, drug delivery & skincare biomaterials.
Poly‑L‑Arginine (PAR)
High‑charge cationic polyamino acid with strong cell‑penetrating & antibacterial properties. Designed for long‑lasting crosslinked hydrogels and intracellular delivery systems.
Poly‑L‑Aspartic Acid (PLA)
Short‑chain anionic polyamino acid, high stability & chelating performance. Suitable for soft tissue fillers, hydrogel modifiers and sustained‑release carriers.
Polysarcosine (PSar)
PEG‑mimicking non‑immunogenic stealth polymer, anti‑protein adsorption. Used for nanoparticle stabilization, HA modification and long‑acting aesthetic materials.
Poly‑L‑Ornithine (PLO)
Mild cationic polyamino acid with ultra‑low cytotoxicity, superior cell adhesion. Ideal for sensitive‑skin biomaterials and nerve cell culture coatings.
Poly‑L‑Lysine (PLL)
Cationic polyamino acid with high positive charge density, antibacterial & cell‑adhesive. Perfect for HA crosslinking, aesthetic hydrogels, gene transfection and antimicrobial coatings.
