A team of researchers has developed a novel method to enhance the precision of cancer treatment using gold nanoparticles tagged with DNA barcodes.

There's a growing body of evidence that gold nanoparticles can offer significant, targeted weight loss that focuses on fat ...

Examples include the use of plant extracts, bacteria, fungi, and biomolecules (e.g., proteins, DNA) as reducing and stabilizing agents. Gold nanoparticles exhibit excellent catalytic activity for ...

Nanoparticle technology is also being investigated as a way of stopping the growth of tumours. Biotech firm Qualigen’s QN-247 drug candidate binds a DNA molecule with a gold nanoparticle and the ...

Tay added, “We used thiol-functionalization to securely anchor the DNA barcodes to the surface of the gold nanoparticles. This ensures the barcodes remain stable, resistant to enzymatic ...

DNA-nanoparticle motors, which convert chemical energy into mechanical motion using a "burnt-bridge" Brownian ratchet mechanism, have been optimized to approach the speed of natural motor proteins.
