Researchers at Tohoku University are harnessing the power of composite polymer particles adorned with gold nanoparticles to deliver more accurate means of testing for, the scientists explain that most testing done today involves antigen-antibody reactions. Fluorescence, absorptions, or colour particle probes are attached to antibodies. When the antibodies stick to a virus such as, these probes visualize the virus’s presence.
Conventional tests that use AU-NP often have to amplify AU-NP’s optical density, so that clinicians can easily measure the strength of the signal produced by the interaction between antibodies and the target substance.is one means to do this. However, because nanoparticles are tiny, it requires a large quantity of them to achieve a strong enough signal for accurate detection.
To overcome this, the Tohoku researchers proposed a new method called self-organized precipitation . SORP works by dissolving polymers into organic solvents before adding a liquid that doesn’t dissolve the polymers well, like water.
In Yabu’s view, these findings reinforce that GNDP particles have broad utility, extending beyond laboratory settings to real-world diagnostic scenarios.Gold prices at a record high are keeping pawn shops busyA stable and highly conductive lithium-ion conductor has been found to address the need for non-sulphide solid electrolytes in solid-state batteries.
