Designing and Introducing New Startegies to Optimize the Molecualr Imprinting Process
… overall binding affinity of molecular imprinting polymers. </p> <p> Imprinted and non-imprinted polymers formed using the new multi-functional monomers showed low numbers of background sites as predicted. However, the reduction in the number of background sites was due to the formation of both …

Surface modification of titanium dioxide and synthesis of non- electroactive coatings by electrochemical polymerization
… salts, and phenol. Except for polymers formed from N-methyl-4-vinyl pyridinium salts, other coatings were shown to be neutral. An anomalous pre-wave, and potential-induced polymer swelling and shrinking phenomena were observed in these coatings. The photocorrosion of small …

Combinatorial Polymer Synthesis and High-Throughput Screening Technology to Identify Optimal Approaches for Mineralized Tissue Engineering
… photopolymerizable and biodegradable materials. Polymers formed from this library were characterized with respect to changes in chemistry, macromer molecular weight, and macromer branching, which all affected the degradation, mechanics, and cellular interactions of the materials. Using set design …

Synthesis and Characterization of Novel Polyethers and Polypeptides for Use in Biomedicine and Magnetic Resonance Imaging
Copolymers that contain terminal or pendent functional groups have great potential in the biomedical area due to their biocompatibility and tunable properties.1-3 In this research, two vinyl functional epoxides, vinyldimethylsilylpropyl glycidyl ether (VSiGE) and ethoxy vinyl glycidyl ether (EVGE), …

The design of cyclodextrins for delivery of siRNA - a structure-activity relationship
… amine. Finally, the potential ability of CD polymers to deliver siRNA was studied. Two cationic β-CD-polymers one functionalised with a primary amine and the other with a quaternary ammonium were used to formulate NPs containing siRNA. Both polymers formed NPs with sizes in the range of 150 …

Interfacial cationic polymerization and its application in microencapsulation
… of the three different drugs by the polymers formed from the four previously mentioned monomers were achieved. Characterization of the polymers, their topographies and permeabilities were carried out using GPC, NMR, FTIR, IR, DSC, SEM, TEM, optical microscopy techniques. From the …

The use of novel poly(allylamine) based amphiphilic polymers for drug delivery.
Fourteen novel comb shaped amphiphilic polymers were successfully synthesised to determine the effect of polymer architecture on the potential of these amphiphilic polymers for hydrophobic drug delivery. Polyallylamine (PAA) was grafted with four different types of hydrophobic pendant groups …

Self-assembly behavior in hydrophilic block copolymers
Block copolymers are receiving increasing attention in the literature. Reports on amphiphilic block copolymers have now established the basis of their self-assembly behavior: aggregate sizes, morphologies and stability can be explained from the absolute and relative block lengths, the nature of the …

Understanding self-assembly and flow heterogeneities in poloxamer wormlike micelles
… (WLMs) are elongated, self-assembled structures formed from amphiphilic molecules in solution. Although the structure of WLMs resembles that of polymers, WLMs are differentiated by their ability to break and recombine at rest and in response to deformations. This unique property has led to their …
