Application

This Poly(2-ethyl-2-oxazoline) polymer is amorphous and water soluble with good temperature stability. Jordan and coworkers showed biocompatibility, no accumulation in tissue, and rapid clearance from the bloodstream1. End-group modified poly(2-ethyl-2-oxazoline)s have been conjugated to peptides2, and were shown as versatile alternatives to poly(ethylene glycol) (PEG) for both protein and small drug conjugation3.

Potential substitute for poly(vinyl alcohol) and poly(vinyl pyrrolidone). Sometimes it is used as an adhesion promoter in coatings. This is also sometimes used in heat sealing and remoistenable hot-melt adhesives. N-propionyl substituted linear polyethylenimine

Features and Benefits

Nonionic, water-soluble thermoplastic. Better heat stability than poly(vinyl alcohol). Good melt flow, shear stability and Newtonian characteristics. Water is a room temperature Theta solvent.

The multifunctional nanoparticles constructed from triphenylamine-poly(lactide-co-glycolide)-poly(ethyleneglycol)-poly(lactide-co-glycolide) (TPA-PEP) and folate-poly(2-ethyl-2oxazoline)-poly(D,L-lactide) (folate-PEOz-PLA) were developed in this study. Iron oxide nanoparticles (IOP) and paclitaxel (PTX) were coencapsulated in the nanoparticles with diameter less than 200 nm. The drug-loaded nanoparticles emit fluorescence peak at

New controlled drug-delivery systems are being explored to overcome the disadvantages of conventional dosage forms. For example, stimulated drug-delivery has been used to overcome the tolerance problems that occur with a constant delivery rate, to mimic the physiological pattern of

Poly(2-oxazoline)s (POx) can be viewed as conformational isomers of polypeptides. They are synthesized via living cationic ringopening polymerization (LCROP) of 2-oxazolines and were almost simultaneously discovered in 1966 by the groups of Litt, Tomalia, Fukui and Seeliger.

The introduction of polymers into the biomedical field has opened new avenues in tissue engineering, implant design, biosensing, and drug delivery.

Wide range of functional polymers for biomedical applications have been synthesized and structurally characterized. Several classes of polymers including biodegradable polymers, hydrophilic & amphiphilic polymers, and stimuli responsive polymers have been prepared using controlled and directed functionalization via "living" polymerization such as RAFT, ionic and ring opening polymerization. Selected polymers have been studied for their structure-properties relationship. "

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
