Nowadays, it is still difficult for molecularly imprinted polymers (MIPs) to achieve homogeneous recognition since they cannot be easily dissolved in organic or aqueous phase. To address this issue, soluble molecularly imprinted nanorods have been synthesized by using soluble polyaniline doped with a functionalized organic protonic acid as the polymer matrix. By employing 1-naphthoic acid as a ...

This paper formulates and solves the inverse dynamics problem of deformable robots made entirely of electro-active polymer gel. One of the primary difficulties with deformable robots is that they have conceptually infinite degrees of freedom. We solve this problem through the selection of an essential point to generate a desired motion. The problem is then reduced to trajectory control of a poi...

In recent years liposomes have gained an increased interest as ingredients for topic formulations, both for their hydratating-humectant properties and as carriers for (trans)dermal delivery of active ingredients that exert their function at cutaneous and/or subcutaneous leve!. In this paper we describe (a) some aspects of liposome use with special regard their to stability in topica! formulatio...

This article will highlight our recent work using conjugated oligomers as precursors to electroactive polymer films and self-assembling nanomaterials. One area of investigation has focused on nonbenzenoid aromaticity in the context of charge delocalization in conjugated polymers. In these studies, polymerizable pi-conjugated units were coupled onto unusual aromatic cores such as methano[10]annu...

Individual multi-walled carbon nanotubes were investigated for their usefulness as nanoscale electrochemical electrodes. The nanotubes were mounted on metal-coated atomic force microscopy tips, and the assembly was insulated with Parylene polymer. Approximately 200nm of the nanotube tip was exposed by use of a laser so the entire probe could be immersed in an electrolytic solution with only the...

We present the use of electroactive polymer actuators as components of a biolab-on-a-chip, which has potential applications in cell-based sensing. This technology takes full advantage of the properties of polypyrrole actuators as well as the wide range of CMOS sensors that can be created. System integration becomes an important issue when developing real applications of EAP technologies. The re...

Drug-eluting stents (DES) have proven to be highly beneficial in that they dramatically reduce the restenosis rates relative to bare metal stents (BmS). Local delivery of antirestenotic drugs from stent scaffolds is achieved through polymeric coatings. The polymers employed are either biostable or bioabsorbable, although, currently, most of the DES that are on the market are based on biostable ...

A new Monte Carlo move for polymer simulations is presented. The “wormhole” move is build out of reptation steps and allows a polymer to reptate through a hole in space; it is able to completely displace a polymer in time N (with N the polymer length) even at high density. This move can be used in a similar way as configurational bias, in particular it allows grand canonical moves, it is applic...

For many years, the idea of a human with bionic muscles immediately conjures up science fiction images of a TV series superhuman character that was implanted with bionic muscles and portrayed with strength and speed far superior to any normal human. As fantastic as this idea may seem, recent developments in electroactive polymers (EAP) may one day make such bionics possible. Polymers that exhib...
