Highly branched poly(β-amino esters) (HPAEs) are developed via a facile and controllable "A2+B3/B2" strategy successfully. As nonviral gene delivery vectors, the performance of HPAEs is superior to the well-studied linear counterpart as well as the leading commercial reagent Superfect. When combined with minicircle DNA construct, HPAEs can achieve ultrahigh(More)
Poly(β-amino ester)s (PAEs) have emerged as a promising class of gene delivery vectors with performances that can even be compared to viruses. However, all of the transfection studies (over 2350 PAEs) have been limited to linear poly(β-amino ester)s (LPAEs) despite increasing evidence that polymer structure significantly affects performance. Herein, we(More)
Nonviral gene therapy holds great promise but has not delivered treatments for clinical application to date. Lack of safe and efficient gene delivery vectors is the major hurdle. Among nonviral gene delivery vectors, poly(β-amino ester)s are one of the most versatile candidates because of their wide monomer availability, high polymer flexibility, and(More)
The replacement of a defective gene with a fully functional copy is the goal of the most basic gene therapy. Recessive dystrophic epidermolysis bullosa (RDEB) is characterised by a lack of adhesion of the epidermis to the dermis. It is an ideal target for gene therapy as all variants of hereditary RDEB are caused by mutations in a single gene, COL7A1,(More)
A knot polymer, poly[bis(2-acryloyl)oxyethyl disulphide-co-2-(dimethylamino) ethyl methacrylate] (DSP), was synthesized, optimized and evaluated as a non-viral vector for gene transfection for skin cells, keratinocytes. With recessive dystrophic epidermolysis bullosa keratinocytes (RDEBK-TA4), the DSP exhibited high transfection efficacy with both Gaussia(More)
Highly branched poly(β-amino ester)s (HPAEs) were designed and synthesised for safe and efficient gene delivery to human keratinocytes. HPAEs outperformed commercial transfection reagents: PEI and SuperFect®, for both transfection efficiency and biocompatibility. A 22 and 3.4 fold enhancement of gene transfection was seen coupled with superior(More)

Using a combined synthesis approach comprising reversible addition fragmentation transfer (RAFT) polymerization and ring opening reaction (ROR), a series of poly glycidyl methacrylate (polyGMA) polymers were designed and synthesized for gene delivery. These polymers characterised by low cationic charge respective to established gene delivery vectors such as(More)
A successful polymeric gene delivery vector is denoted by both transfection efficiency and biocompatibility. However, the existing vectors with combined high efficacy and minimal toxicity still fall short. The most widely used polyethylene imine (PEI), polyamidoamine (PAMAM) and poly(dimethylaminoethyl methacrylate) (PDMAEMA) suffer from the correlation:(More)
