New patent: The method of silver nanoparticles immobilization onto solid substrates
The leading scientist of the RCPTM centre, prof. Radek Zbořil, achieved in cooperation with Dr. Jana Soukupová significant advancement in the field of the reproducible preparation of polymer coatings with covalently bonded silver nanoparticles which exhibit high antibacterial activity. These coatings may be used for antibacterial treatment many surfaces in clinical practice (e.g. surface of catheters). The patent application of this method was granted by national authority of the Czech Republic in 2012 (No. of patent 303502).
The newly developed method of the reproducible preparation of the high effective SERS substrate
The newly developed method of the reproducible preparation of the high effective SERS substrate was used by Dr. Vaclav Ranc from the research team of RCPTM centre for detection of biological active molecules at very low concentration of femtomolar level. This study was published in the Journal of Raman spectroscopy 2012.
Reproducible discrimination between Gram-positive and Gram-negative bacteria using surface enhanced Raman spectroscopy with infrared excitation
Dr. Robert Prucek member of the RCPTM research team made an important step on the way to the development of the fast and reliable method of bacteria detection using SERS method. The results of the study aimed at reproducible discrimination between Gram-positive and Gram-negative bacteria were published in RSC journal Analyst 2012.
Environmental Friendly Nanotechnologies and Biotechnologies in Water and Soil Treatment
RCPTM proudly announces the new project called “Environmental Friendly Nanotechnologies and Biotechnologies in Water and Soil Treatment” with total costs 14 mil EUR in 8 years. Project intention is to establish the NANOBIOWAT Center connecting potentials of 3 academic and 6 industrial subjects in order to develop and implement ecologically friendly nanotechnologies and biotechnologies for water and soil treatment.

 Water dispersion of silver nanoparticles exhibits a typical orange-yellow colour which vanishes as the size of nanoparticles exceeds above 100 nm.  Electron microscopic image of silver nanoparticles synthesized by the modified Tollens method.  Examples of organisms for which the toxicity of silver nanoparticles has been tested: Paramecium caudatum (left), Drosophila melanogaste (middle) and Scenedesmus subspicatus (right). |
