Spotlight May 2023: Dual energy – edible batteries
An Italian research group reports on edible batteries that supply electric current and can be digested as food, thus providing energy a second time. What sounds funny at first has a serious background, because in medicine, power sources are needed that could be transported through the digestive tract and possibly remain in the body unintentionally, e.g., for swallowable mini-cameras that could be used in gastroscopies and colonoscopies. If the battery materials are then digestible, there will be no problematic effects from the battery if it does not pass through the body quickly enough.
The battery presented is composed of dietary and nutritional supplements, and since all components are either digestible or pass through the body unchanged, they could actually be eaten. The authors did test the battery’s functionality, so it does provide electricity, but they did not eat their battery because the battery case was too large and not constructed of digestible materials, so more research is needed here.

Spotlight October 2020: Nanosafety – Topic of the Future
Research on nanosafety is a driver of innovation as the spotlight in July has demonstrated. But furthermore, this research field is built on routine as well if researchers look for the “needle in the haystack”. In many areas the safety research initiates the development of new methods, e.g. for the determination of nanoparticles within exposed organisms via […]

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 […]

Plastic pollution has become a significant threat to the oceans, biodiversity, and ecosystems worldwide. Despite efforts to reduce plastic consumption, escalating plastic production continues to increase the magnitude of plastic pollution in the environment. In response to this crisis, the UN-Environmental Assembly (Link) adopted a resolution in March 2022 to develop a legally binding treaty […]

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 […]
