Safe-by-design: A fast and sensitive method for nanoparticle screening


Engineered nanomaterials (ENMs) are of high innovative potential with a large number of possible applications in a variety of fields (e.g., electronics, energy generation and storage, photonics, diagnostics or as drug delivery agents). The large-scale use of ENMs raises concerns about their safety for humans and the environment.
A large variety of methods are available for analyzing the properties of ENMs and observing their fate in biological and ecological systems. Common attributes of these methods are: i) high price for analysis and instrumentation, ii) complex data analysis, iii) complex sample preparation.

A new approach for the analysis of ENMs will be presented, based on the analysis of heat produced by light-stimulation. The method is easy-to-use, does not require complex sample preparation of data analysis and can be used for a fast screening of ENM presence, dispersion states and other properties.


Christoph Geers holds a BSc. in Biotechnology and a MSc. in Biomedical Engineering. He received his PhD degree from the Adolphe Merkle Institute in Fribourg (Switzerland), investigating the interactions of nanoparticles with wood.

Mr. Geers is enrolled in a postgraduate study program on Translational Medicine and Entrepreneurship at the Swiss Institute for Translation and Entrepreneurship in Medicine (SITEM) in Bern.

Since February 2018, Mr. Geers has co-founded the start-up NanoLockin GmbH together with 3 colleagues where he is the managing director.
