Special Issue Information

Dear Colleagues,

Polymers have gained ever-increasing interest over the past few decades as a new class of material and have been widely investigated as fulfilling a longing for emerging materials that are essential in modern science and engineering. Taking advantage of the development of polymer science to date, we design and synthesize various polymer architectures via synthetic methodologies, which exhibit fascinating physical properties, and further apply them to many fields with the aid of theoretical elucidation and precise processing. In particular, a merger with nanoscience and nanotechnology enables to build up an integrated system via a bottom-up approach, which allows to explore unprecedented phenomena emanated from polymeric materials and opens up completely new applications. Therefore, now we are able to envisage or comprehend a sophisticated, polymeric system with artificial intelligence that senses rapidly any specific target and functions autonomously while adapting themselves to a new environment—as an example. Motivated by remarkable growth and great potential of polymers, we hope to look at prospective objectives of polymer science by collecting contributions on the latest researches and perspectives, and thus, edit this Special Issue as an up-to-date user guide to recent polymer nanoscience and nanotechnology, which will benefit readers not only in academia but also in industry and ultimately give rise to future advances.

This Special Issue covers broad topics on polymer nanoscience and nanotechnology in the context of fundamental and applied sciences (e.g., synthetic chemistry, polymer physics and theory, nanoscale analysis, materials application, or processing; but not limited to them). Interdisciplinary approaches are also welcomed. The Special Issue will publish full research papers, communications, and reviews.

Conducting polymers (CPs) have attracted significant attention in a variety of research fields, particularly in biomedical engineering, because of the ease in controlling their morphology, their high chemical and environmental stability, and their biocompatibility, as well as their unique optical and electrical properties. In particular, the electrical properties of CPs can be simply tuned over the full range from insulator to metal via a doping process, such as chemical, electrochemical, charge injection, and photo-doping. Over the past few decades, remarkable progress has been made in biomedical research including biosensors, tissue engineering, artificial muscles, and drug delivery, as CPs have been utilized as a key component in these fields. In this article, we review CPs from the perspective of biomedical engineering. Specifically, representative biomedical applications of CPs are briefly summarized: biosensors, tissue engineering, artificial muscles, and drug delivery. The motivation for use of and the main function of CPs in these fields above are discussed. Finally, we highlight the technical and scientific challenges regarding electrical conductivity, biodegradability, hydrophilicity, and the loading capacity of biomolecules that are faced by CPs for future work. This is followed by several strategies to overcome these drawbacks. Full article

Over the past twenty years, photoacoustics—also called optoacoustics—have been widely investigated and, in particular, extensively applied in biomedical imaging as an emerging modality. Photoacoustic imaging (PAI) detects an ultrasound wave that is generated via photoexcitation and thermoelastic expansion by a short nanosecond laser pulse, which significantly reduces light and acoustic scattering, more than in other typical optical imaging and renders high-resolution tomographic images with preserving high absorption contrast with deep penetration depth. In addition, PAI provides anatomical and physiological parameters in non-invasive manner. Over the past two decades, this technique has been remarkably developed in the sense of instrumentation and contrast agent materials. In this review, we briefly introduce state-of-the-art multiscale imaging systems and summarize recent progress on exogenous bio-compatible and -degradable agents that address biomedical application and clinical practice.
