Bionanotechnology can remove antibiotic resistant bacteria from hospital wastewater

Posted on 17 September 2015

dws-wur-bionano-felder-lab-research-770px“We are developing a nanoplatform that has sensor molecules and nanoparticles that should be able to remove antibiotic resistant bacteria from hospital wastewater”, revealed professor Aldrik Felder of the Bionanotechnology Group of Wageningen University.

Felder mentioned the particular application as an example in his inaugural lecture on 17 September.

“Molecules on nanoparticle that can interact with other molecules”, Felder explained. “New particles that never existed before and we can now monitor their interactions with biological systems. That opens a world of new applications”.

To capture antibiotic resistant bacteria his group is developing a nanoplatform that can recognize special molecules and ultimately remove antibiotic resistant bacteria from hospital wastewater.

According to Felder this technology is already used for biomedical diagnostics.

Level of alchemists
Felder compared the current knowledge of bionanotechnology to the knowledge of the alchemists at the beginning of the renaissance.

It is therefore important that all nanoparticles, either spontaneously formed or man-made, are well characterized. We must characterize their optical absorbance and fluorescence, and magnetic resonance spectroscopy.”

Felder suggested to develop a periodic system of nanoparticles, as there is for all the chemical elements. “We now know only a few classes of particles but have little predictive values. We also do not yet know how nanoparticles behave in biological systems”, he said.
