The human exposure to metal pollutants and risk factors are recognized causes of health problems and disease burden at all ages.
To tackle this problem biomonitoring focused on the use of biomarkers is a very appealing approach to screen individuals and anticipate risks of developing diseases. Also, to estimate the response of cells to metal-containing nanoparticles, pollutants and metallo-drugs is a first important step towards an understanding of their effects on the entire organism.
On this background it is very important to gain insight in i) the metal compounds incorporation in cells and their toxicity; ii) possible target molecules; and iii) cell functions that may be target by these compounds.
Our current projects within this subject include
- Development of new imaging modality using fast ion beams. We can currently obtain real three-dimensional images of whole cells with tens of nanometre depth resolution, which is particularly appropriated to the ongoing studies on the interaction of particulate matter (indoor and outdoor pollution), metallo-drugs and nanoparticles with cells, microorganisms and microbial structures [1,2,3].
- Estimate the potential toxicological effect of indoor particulate matter sources evaluating in vitro the biological response towards human cell line model. This is crucial to devise cost-effective abatement strategies and contribute to assess and identify sustainable solutions for ecosystems and the population and support the transition to a low carbon economy.
- Search of new biomarkers for noncommunicable diseases by screening individuals and their response to intervention and by using laboratory models to unravel the mode of action of those biomarkers [4,5].
