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 November 2020: Nanotechnology in the public perception
In November, we would like to draw your attention to a publication that examines public perception of the safety of nanomaterials in Austria.It shows, that although there is generally a rather positive attitude towards nanomaterials, there are different opinions on safety issues from different social groups. Further clarification seems necessary. Despite the widespread use of […]

Plastic pollution is a global problem that will continue to affect humanity for more than 100 years. There is the visible pollution, e.g. plastic debris in the environment, which leads to death for many animals (because they mistakenly think the plastic is food and eat it or because they get caught in the plastic waste).

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 […]

The use of nanomaterials in 3D printing has great potential. Due to the properties of nanoscale materials, many requirements can be implemented in 3D printing. However, these unique properties based on the size of the particles also lead to the need for new risk assessments. This is because if the nanoparticles are released in the […]
