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 ...

Tay added, “We used thiol-functionalization to securely anchor the DNA barcodes to the surface of the gold nanoparticles.

DNA is often used as a system for organizing other materials than DNA to somewhat lower resolution than the crystallographic ideal. Gold nanoparticles, proteins, viruses, and other nanoscale species ...

nanoparticles with a higher density of surface charge resulted in a greater degree of membrane gelation, whereas DNA, which is a flexible rod-like molecule, did not induce this effect. The ...

Gold nanoparticles are also being used in the fight ... Biotech firm Qualigen’s QN-247 drug candidate binds a DNA molecule with a gold nanoparticle and the precious metal has been shown to ...

A breakthrough in safely delivering therapeutic DNA to cells could transform treatment for millions suffering from common chronic diseases like heart disease, diabetes, and cancer. A new process ...

And they signal the oil-rich emirate’s investment in a powerful, and potentially highly profitable, new resource: its citizens’ DNA. Abu Dhabi ... Programme a “gold mine of data”.

“There are an enormous number of people using gold nanoparticles,” says Chad Mirkin, a chemist at Northwestern University whose own studies focus on how the particles could help turn off genes ...
