Special Issue Information

Dear Colleagues,

Nanostructured polymers are generally reported as nanoscale polymers or polymer composites containing nanomaterials, and have become in the past few years the materials of choice for the design of new electrochemical devices. These materials combine structural versatility and functionality with mechanical strength that can be tailored to meet the needs of the target application.

This Special Issue aims to give an overview of recent developments in nanostructured polymeric materials and composites in connection with their application as new materials for advanced electrochemical devices, which include energy conversion and storage devices (batteries, fuel cells, electrochemical capacitors), chemical sensors, optoelectronic devices, and biomedical applications. Potential topics include, but are not limited to significant new findings related to the synthesis, nanoscale properties and morphology, performance, and technological applications of novel nanopolymeric materials and componentry for such devices. Authors are welcome to submit their latest research in the form of original full articles, short communications, or reviews on this topic.

Nanoparticle (NP) concentration is crucial for liquid biopsies and analysis, and various NP concentrators (NPCs) have been developed. Methods using ion concentration polarization (ICP), an electrochemical phenomenon based on NPCs consisting of microchannels, have attracted attention because samples can be non-invasively concentrated using devices with simple structures. The fabrication of such NPCs is limited by the need for lithography, requiring special equipment and time. To overcome this, we reported a rapid prototyping method for NPCs by extending the previously developed hydrogel molding method, a microchannel fabrication method using hydrogel as a mold. With this, we fabricated NPCs with both straight and branched channels, typical NPC configurations. The generation of ICP was verified, and an NP concentration test was performed using dispersions of negatively and positively charged NPs. In the straight-channel NPC, negatively and positively charged NPs were concentrated >50-fold and >25-fold the original concentration, respectively. To our knowledge, this is the first report of NP concentration via ICP in a straight-channel NPC. Using a branched-channel NPC, maximum concentration rates of 2.0-fold and 1.7-fold were obtained with negatively and positively charged NPs, respectively, similar to those obtained with NPCs fabricated through conventional lithography. This rapid prototyping method is expected to promote the development of NPCs for liquid biopsy and analysis. Full article
