Discovering the 'nanosciences' with nanotechnology

Experts at the University of Central Florida have developed a method for rapidly identifying pathogens involving intestinal inflammation in the patient's body.

New nanoparticle techniques can detect many other bacteria that have challenged scientists for centuries because they hide in human tissues and reprogram cells to hide. Avoid the immune system.

These bacteria are re-exported after several years and can cause serious health problems such as TB in patients. Currently there are many methods of screening to detect bacteria but it requires very time consuming but not effective.

Researchers Manuel Perez and Saleh Naser and their colleagues use nanoparticles coated with DNA markers that characterize fugitive pathogens that can detect pathogens with high efficacy in a short time.

When these nanostats bind to the DNA of the pathogen, the magnetic signal is detected, which is amplified by the water molecules surrounding the nanoparticles. Researchers can then read the change in magnetic signatures on the computer screen or a portable electronic device such as a smartphone, and determine if the sample is contaminated with the instrument. whether or not.
