Liver Cancer Diagnosis Made Possible With Gold Nanoparticles!

Tumors in the Liver (White Clumps)Liver cancer or hepatocellular carcinoma is one of the most debilitating cancers that can kill most of the affected individuals within a 6 month period due to poor diagnosis.

Diagnostic procedures currently available (MRI and CT scans, ultrasound) cannot detect the presence of the tumor until it spreads in diameter by 5 cm (centimeters) which has already reached an aggressive and untreatable stage.

To overcome this problem, a group of researchers from Brown University have come up with a new diagnostic technique that can detect the presence of tumor which is as small as 5 mm (millimeters) in diameter.

The study involved gold nanoparticles of 10 nm and 50 nm (nanometers) in diameter, which were then ringed with 2 polyelectrolyte coatings of 1 nm in diameter. This coating gave the gold nanoparticles the required charge which increased their chance of getting surrounded by tumor cells. The team then used X-ray scatter imaging to observe the gold particles within the tumor cells.

With further clinical investigation, this method of diagnosis can save thousands of lives from dreadful liver cancer.
