Nanoparticles for polishing teeth
Image obtained from medescape.wordpress.com
Researchers at Clarkson University Centre for Advanced Materials Processing have developed a method for dental protection against cavities by grinding with ultrafine particles of silica.
In conducting this project, they adapted a polish technology used in the semiconductor industry to polish the roughness of the teeth at nanoscale. Roughness remaining in teeth after the refinement is a few nanometers.
This project’s contribution is not the use of silica for dental polishing used before but its nanoscale use.
According to the authors of this study, this technique is an effective preventive tool against bacteria responsible for the destruction of tooth enamel, which poses major problems of grip making it easier to eliminate the bacteria before they cause damage to the enamel.

INL – News
New INL researcher Marta Prado
Marta Prado is INL´s latest researcher and has just settled in in Braga. She has an advanced degree in Food Science and Technology and studies in Biology Science from the University of Santiago de Compostela (Spain). Marta has a PhD from the same university in the program of Nutrition, Bromatology and Food technology.
Between the years 1999 and 2006, our new Spanish colleague has been working as a researcher in the Faculty of Veterinary Sciences (Lugo, Spain) from the University of Santiago de Compostela (USC). Between 2006 and 2010, she has been working as Scientific Officer in the Institute of Reference Materials and Measurements from the Joint Research Centre of the European Commission (EC-JRC-IRMM) in Geel, Belgium.
Most of her research experience is related with genomic analysis tools and its application to food analysis, since she had worked on the development and optimization of PCR-based methods for the control of food and animal feeds. In the INL, she will work on the application of magnetic nanobiosensors for the detection of ruminant origin meals in feed.
