Controlling poly(beta-amino ester) network properties through macromer branching.
Photopolymerizable and degradable biomaterials are becoming important in the development of advanced materials in the fields of tissue engineering, drug delivery, and microdevices. We have recently developed a library of poly(beta-amino ester)s (PBAEs) that form networks with a wide range of mechanical properties and degradation rates that are controlled by simple alterations in the macromer mo...
متن کاملEvaluating the potential of poly(beta-amino ester) nanoparticles for reprogramming human fibroblasts to become induced pluripotent stem cells
BACKGROUND Gene delivery can potentially be used as a therapeutic for treating genetic diseases, including neurodegenerative diseases, as well as an enabling technology for regenerative medicine. A central challenge in many gene delivery applications is having a safe and effective delivery method. We evaluated the use of a biodegradable poly(beta-amino ester) nanoparticle-based nonviral protoco...
متن کاملEsterase- and pH-responsive poly(β-amino ester)-capped mesoporous silica nanoparticles for drug delivery.
Gating of mesoporous silica nanoparticles (MSNs) with the stimuli-responsive poly(β-amino ester) has been achieved. This hybrid nanocarrier releases doxorubicin (DOX) under acidic conditions or in the presence of porcine liver esterase. The DOX loaded poly(β-amino ester)-capped MSNs reduce cell viability when tested on MDA-MB-231 human breast cancer cells.
متن کاملDual Stimuli-Responsive Poly(β-amino ester) Nanoparticles for On-Demand Burst Release.
We designed poly(β-amino esters) (PBAEs) bearing both UV light- and pH-sensitive groups and used PBAEs to prepare nanoparticles (NPs) that can be utilized for on-demand burst release of guest molecules in response to multiple triggers. Due to the presence of the photo-cleavable group in each repeating unit of PBAE, rapid release of encapsulated model drug could be achieved even with exposures t...
متن کاملA bioreducible linear poly(β-amino ester) for siRNA delivery.
Described here is the synthesis and characterization of a novel, bioreducible linear poly(β-amino ester) designed to condense siRNA into nanoparticles and efficiently release it upon entering the cytoplasm. Delivery of siRNA using this polymer achieved near-complete knockdown of a fluorescent marker gene in primary human glioblastoma cells with no cytotoxicity.
