Nanoteknologi

Als Bereich der Entwicklung und Verwendung von Nanotechnologien zur Heilung von Krankheiten ist die Nanomedizin eng mit den Erwartungen auf die Verwirklichung des Potentials der Nanotechnologien zur Verbesserung der menschlichen Gesundheit einerseits und zur Gewährleistung des gesellschaftlichen Wohlstandes andererseits verbunden. Ziel dieser Rhetorik ist es, die Einbeziehung der Nanomedizin in die soziale Arbeit unterschiedlicher Akteure zu normalisieren. Die Translation in der Nanomedizin ist der Ausdruck, der eine solche Entwicklung bezeichnet.Auf der Grundlage der Theorie der Relation wird diese Translation empirisch mit Hilfe von Topic-Modell-Verfahren untersucht. Dabei zeigt sich, dass die Translation in der Nanomedizin, welche als Weg "par excellence" zur effizienteren Heilung von Patienten vorgesehen war, im Laufe der Zeit insbesondere zur Formalisierung des Verhältnisses zwischen Krankheiten und Menschen zum Zweck der Verdatung eines solchen Verhältnisses verwendet wird.

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience.Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.The chapter "e;Aggregation-Induced Emission In Electrochemiluminescence: Advances and Perspectives"e; is available open access under a CC BY 4.0 License via link.springer.com.

This book is intended to serve as an authoritative reference source for a broad audience involved in the research, teaching, learning, and practice of nanotechnology in immunotherapy. The combination of nanotechnology and immunotherapy is recognized as a promising treatment modality. In particular, the use of nanoparticles in immunotherapy has attracted increased attention for their unique efficacy and specificity in cancer treatment. A wide variety of nanoparticles, such as polymeric and liposomal nanosystems, carbon nanotubes, and gold nanoparticles have provided important nanoplatforms for immunotherapeutic approaches. They have been shown to improve delivery and efficacy of immunotherapeutic agents such as vaccines or adjuvants.Nanoparticle-mediated thermal therapy has demonstrated the effectiveness for precise tumor cell ablation, radio-sensitization of hypoxic regions, enhancement of drug delivery, activation of thermosensitive agents, and enhancement of the immune system. Plasmonic nanoparticles are a special type of metallic nanoparticles that has received great interest due to their enhanced optical and electromagnetic properties and their superior capacity to convert photon energy into heat for selective photothermal therapy at the nanoscale level. Nanoparticle sizes can also be controlled such that they accumulate preferentially in tumors due to the enhanced permeability and retention effect of tumor vasculature. Various nanosystems such as gold nanoparticles have also been shown to stimulate the immune system.Immunotherapies could thus synergistically benefit from the combination with targeted nanoparticle-mediated photothermal therapies, especially when hyperthermia around immune-checkpoint inhibitors in the tumor bed is combined with precise thermal ablation of cancer cells. Of great importance is the possibility that such an approach can induce long-term immunological memory that can provide protection against tumor recurrence long after treatment of the initial tumors, like an 'anticancer vaccine'. Nanoparticle-mediated immunotherapy could lead to an entirely new treatment paradigm that challenges traditional surgical resection approaches for many cancers and metastases.
