Nanotechnology for antibiotics effectiveness applications
7 February 2009Bacteria such as Golden Staph or MRSA are causing many health problems to the communities and it has been observed in the recent past that these bacteria are becoming increasingly resistant to antibiotics and therefore posing a major threat.
Now a group of scientists from London Center for Nanotechnology and University of Queenslands are working together for finding a suitable solution of the problem with the help of Nanotechnology. Researchers will use tiny nano-probes and will try to understand the mechanism of effectiveness of antibiotic on bacteria.
Researchers working on a $4 million Australian Fellowship will help in developing antibiotics and antifungals that are effective in killing and slowing down the growth of resistant bacteria. Researchers made nano-probes and coated these probes with molecules found in normal bacteria and antibiotic resistant bacteria. Once they added doses of antibiotic vancomycin to the system, they found that the probes from normal bacteria were stressed clearly indicating that the drug is effective in controlling the bacteria, howeverthe probes from resistant bacteria were weakly affected indicating that the bacteria is resistant to vancomycin.
Researchers found that there is a very small difference between resistant and non-resistant bacteria and with the help of these nano-probes, the difference can be identified within few minutes. With the help of these nano-probes, researchers are finding other antibiotic drugs those can weaken the structure of resistant bacteria so that novel antibiotics are developed.

Dear Dr
It is my pleasure to resive this typle of propes for research, I would liketo use this probes for detection of antibiotics in blood and tissues to identify the passage and presence of certain antibiotic in blood or milk or tissues
So please send me types probes and bacteria
Thank you
