Nanomedicine Drugs can be made smarter

An innovative technique has been established to make drugs smarter using nanotechnology so they will be more operative at reaching their target. Scientists have formulated a new method to decorate gold nanoparticles with a protein of choice so they can be used to tailor drug to more accurately target an area on the body, such as a cancer tumor.

Gold nanoparticles are spheres made of gold atoms having a diameter of only few billionths of a metre which can be coated with a biological protein and combined with drugs to enable the treatment to travel through the body and reach the affected area.

The nanoparticles can adsorb (hold on its surface) drugs which would otherwise become insoluble or quickly degrade in the blood stream, and due to their small size they can overcome biological barriers such as membranes, skin and the small intestine which would usually prevent the drug from reaching its target.

The technology is already used in real world applications such as pregnancy tests -- where gold nanoparticles decorated with an antibody against the hormone present in the urine of pregnant women is added to the 'positive' strip so it reacts with the nanoparticles to turn the stick red -- but is not yet widely used in drug development.ME Conferences inviting the participants all over the globe to share their research at INTERNATIONLAL CONFERENCE ON NANOMEDICINE AND NANOTECHNOLOGY IN HEALTH CARE scheduled during MAY 27-28, 2019, ISTANBUL, TURKEY
