The triblock copolymer is composed of two identical hydrophilic segments: Monomethoxy poly(ethylene glycol) (mPEG) and one hydrophobic segment poly(ε‑caprolactone) (PCL); which is synthesized by coupling of mPEG-PCL-OH and mPEG‑COOH in a mild condition using dicyclohexylcarbodiimide and 4-dimethylamino pyridine. The amphiphilic block copolymer can self-assemble into nanoscopic micelles to accom...
The administration of poorly water-soluble drugs represents a relevant problem due to the low body fluids transport efficiency through hydrophilic hydrogels. Star-shaped co-polymers, i.e., amphiphilic polymers such as those with hydrophobic core and outer shell, can be used improve weak interactions drugs, benefits in terms controlled delivery. In this work, two different four-arm star-shaped P...
Many human skin diseases, such as seborrheic dermatitis, potentially occur due to the over-growth of fungi. It remains a challenge to develop fungicides with a lower risk of generating resistant fungi and non-specifically killing commensal microbes. Our probiotic approaches using a selective fermentation initiator of skin commensal bacteria, fermentation metabolites or their derivatives provide...
BACKGROUND In this paper, a series of amphiphilic triblock copolymers based on polyethylene glycol-poly ɛ-caprolactone-polyethylenimine (mPEG-PCL-g-PEI) were successfully synthesized, and their application for codelivery of chemotherapeutic drugs and DNA simultaneously was investigated. METHODS AND RESULTS These copolymers could self-assemble into micelles with positive charges. The size and ...
A type of multi-sensitive ABC-CBA block copolymer with thermal, glutathione and pH-responsive bonds was synthesized via ring opening polymerization along cationic mechanisms. In continuum, the strands self-assembled into nanomicelles. The linear is comprised poly (methoxy ethylene glycol)-b-poly (2-ethyl-2-oxazoline)-b-poly (?-caprolactone)-cystamine (i.e. [mPEG-b-PEtOz-PCL]2-Cys) curcumin enca...
