The COVID 19 outbreak has led to a fundamental rethinking of existing approaches to diagnosis, treatment, and prevention methods. The need for better and more efficient concepts is global and urgent. Nanotechnology has long been at the forefront of innovation and has led to advances in many different disciplines. Could this interdisciplinary field help develop a more comprehensive approach to combating COVID-19 as well as future pandemics?
This review published in the journal ACS NANO provides a general introduction to the novel coronavirus (SARS-CoV-2), the progression of the coronavirus disease 2019 (COVID-19) along with an overview of current vaccines. Additionally, some of the attempts to stop the first interaction of the virus with the target cells as well as preventing life-threatening processes are illustrated in detail. In this context, the interdisciplinary authors present and discuss several potential advantages of nanotechnology and the critical role it could have in the fight against COVID-19 and future pandemics both inside and outside the host. The authors highlight the multifunctional solutions offered by materials in the nanoscale e.g., by combining diagnostic and therapeutic into one. These nanotechnology-based-systems can increase the specificity and therefore the efficiency of immunosuppressant delivery to targeted cells resulting in a reduction of drug dose and drug distribution to nontarget organs. The authors also explain in detail the multiple ways, nanomaterials can assist vaccines or immunization research for example by boosting the upregulation required by the immune system or redirecting the immune response against antigens. Nanotechnology may similarly offer pathways to slow the spread of COVID-19; in this review, the development of self-disinfecting surfaces that would avoid contamination at hospitals or homes is also presented. Finally, to highlight the multifunctionality of nanomaterials, the authors examine how nanotechnology-based solutions could increase the safety of air-filtering devices such as masks.

Spotlight August 2021: Towards FAIR nanosafety data
In August we would like to present a paper on FAIR data. The paper published in Nature Nanotechnology in June 2021 summarises the challenges and provides recommendations for the efficient reuse of nanosafety data in line with the recently established FAIR guiding principles: findable, accessible, interoperable and reusable. This article summarises the know-how on the […]Read more
Spotlight Juli 2020: “Nanosafety – More than just regulatory processes”
Nanosafety is more than just a compulsory aspect of nanomaterials research and regulation. This research area also has great potential to drive new innovations. It is exactly this perspective that is addressed in the special issue “Rethinking Nanosafety: Harnessing Progress and Driving Innovation” by Chen et al. 2020. The article illustrates that especially in the field of […]Read more
Spotlight April 2021: Nanomaterials and Fake News – a commentary based on an example
In February 2021, the article “The invisible killer lurking in our consumer products” appeared, describing nanoparticles as a greater danger than Corona . “The use of nanomaterials” would be “unregulated” and “nanomaterials are so small that they cannot be determined once they are part of a product”. So what is the truth of these statements? […]Read more
