BACKGROUND The purpose of this study was to test the efficacy of cyclic Arg-Gly-Asp (RGD) peptide conjugated with polyionic complex nanomicelles as targeted therapy for glioma. METHODS A stable cyclic RGD polyionic complex nanostructure, ie, a c(RGDfC) polyionic complex micelle, was synthesized and its biocompatibility with cultured neurons was assessed using a cell viability assay. Targeted ...

Abstract Cellulose–poly(ferrocenylsilane) (PFS) polyionic liquid (PIL) composite sponges are fabricated by codissolution of cellulose and PFS‐PIL, followed solvent exchange freeze‐drying. The hybrid used to in situ produce immobilize palladium nanoparticles (Pd NPs), leading Pd NP‐decorated porous supports. formation NPs is confirmed TEM XPS measurements. as‐prepared cellulose/PFS‐PIL@Pd exhibi...

In response to advances in proteomics research and the use of proteins in medical and biotechnological applications, recombinant protein production and the design of specific protein characteristics and functions has become a widely used technology. In this context, protein fusion tags have been developed as indispensable tools for protein expression, purification, and the design of functionali...

The preparation of monolithic polyionic supports which serve as efficient heterogeneous supports for palladium(0) nanoparticles is described. These functionalized polymers were incorporated inside a flow reactor and employed in Suzuki-Miyaura and Heck cross couplings under continuous flow conditions.

A great majority of “interesting” compounds in fluorine and noble gas chemistry are thermodynamically unstable, highly oxidative and thus hard to isolate and characterize materials. Since the ultimate characterization structural determination is very often related to a route to crystalline products, the aforementioned unique properties severely restrict the choice of a solvent for these compoun...

Corrosion is a deterioration of a metal due to reaction with environment. The use of corrosion inhibitors is one of the most effective ways of protecting metal surfaces against corrosion. Their effectiveness is related to the chemical composition, their molecular structures and affinities for adsorption on the metal surface. This review focuses on the potential of ionic liquid, polyionic liquid...

Mucus is an ubiquitous polymer hydrogel that functions as a protective coat on the surface of integument and mucosa of species ranging from simple animals (such as coelenterates) to mammals. The polymer matrix of mucus is made out of long-chain glycoproteins called mucins that are tangled together, forming a randomly woven, highly polyionic network (Lee et al., 1977; Verdugo et al., 1983). Muci...

Ionic liquid based systems are used to facilitate the cationic polymerization of isobutylene conventional grade polyisobutylene (PIB) using AlCl3 as an initiator. Specifically, compound 1-butyl-3-methylimidazolium chloride (IL) is employed a reference system due its simplicity, well polyionic (PIL), prepared via radical 1-butyl-3-vinylimidazolium chloride, and halloysite clay (Hal) supported io...

In the current issue of ACS Nano, Löbling, Haataja et al. craft polymeric nanoparticles with a hierarchy of nontrivial surface structures by combining conventional interpolyelectrolyte complexation with steric control from an uncharged copolymer block. Remarkable cylindrical and lamellar nanodomains are produced on the polyionic coronae of spherical micelles. Here, we discuss generalizing this ...
