The use of polymeric nanoparticles as drug delivery devices is becoming increasingly prevalent in a variety of therapeutic applications. Despite their widespread clinical use, the factors influencing the release profiles of nanoparticle-encapsulated drugs are still not quantitatively understood. We present here a new, semi-empirical model of drug release from polymeric nanoparticles using a for...

Spinal cord injury (SCI) commonly leads to lifelong disability due to the limited regenerative capacity of the adult central nervous system. Nanomicelles can be used as therapeutic systems to provide effective treatments for SCI. In this study, a novel triblock monomethyl poly(ethylene glycol)-poly(l-lactide)-poly(trimethylene carbonate) copolymer was successfully synthesized. Next, polymeric n...

Functional multilayer thin films have been prepared by layer-by-layer (LbL) deposition for the development of sensors, separators, and drug delivery systems. In particular, glucose-sensitive LbL films have been widely studied for use as glucose sensors and in glucose-triggered drug delivery systems. In this work, I report on glucose-sensitive LbL films that consist of concanavalin A (ConA), phe...

A one-pot ultrasonic procedure has been developed as a versatile route for synthesizing polymer-coated microspheres that have potential application as drug delivery vehicles. The use of synthetic thiolated poly(methacrylic acid) macromolecules as the shell material offers control over size, morphology and functionality of the microspheres.

Paclitaxel, a polyol chemotherapeutic agent, was covalently conjugated through its 2'-OH to polylactide with 100% regioselectivity via controlled polymerization of lactide mediated by paclitaxel/(BDI-II)ZnN(TMS)(2) (BDI-II = 2-((2,6-diisopropylphenyl)amino)-4-((2,6-diisopropylphenyl)imino)-2-pentene). The steric bulk of the substituents on the N-aryl groups of the BDI ligand drastically affecte...

Methods The primary goal of the new RA is to implement the principle of economical production. This should be kept in mind, while interpreting its content, because the act allows one to approach to each drug individually. At the beginning one needs to find a comparator currently financed with the best outcomes/cost ratio. The next step is to search for RCTs proving the superiority of the propos...

Biodegradable micelle systems with both extracellular stabilities and specific targeting properties are highly desirable for anti-cancer drug delivery. Here, we report a biodegradable and crosslinkable poly(propylene fumarate)-co-poly(lactide-co-glycolide)-co-poly(ethylene glycol) (PPF-PLGA-PEG) copolymer conjugated with folate (FA) molecules for receptor-mediated delivery of doxorubicin. Micel...

A general and simple method was presented for preparing supramolecular hydrogels to deliver anticancer drugs. In this system, hydrophobic anticancer drug doxorubicin (Dox) was loaded into poly(ethylene glycol)-b-poly(ε-caprolactone) (PEG-b-PCL) amphiphilic block copolymer micelles by hydrophobic interaction. The drug loaded micelles were then mixed with α-cyclodextrin (α-CD) solution to generat...
