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.

Science has always taken nature as a model and imitated it. If you look at the field of photonics, i.e. the use of optical technologies for information processing, transmission or storage, the colorful examples in the animal and plant world are perfect basic drawers for technical applications. While colors in nature are used either for […]

In January, we present a paper published in the Nature Journal communications materials. The article focuses on the development of a new detection method of nanopolystyrene. The method not only makes it possible to detect nanoplastics in the environment for the first time, but also to determine their accumulation in plants and animals. Nanoplastics, which […]

In August, we would like to present a paper of the German BMBF project nanoGRAVUR. nanoGRAVUR dealt from 2015-2018 with the grouping of nanostructured materials with regard to occupational safety, consumer and environmental protection and risk mitigation. The approach is now described by the project partners in this paper.Due to the variety of synthetic nanomaterials and the numerous modifications (differences in size, shape, chemical composition and surface functionalization), the effort required to investigate effects and behaviour within the framework of regulatory requirements is…
