Gold nanoparticle: a novel tool for DNA and protein detection.

Abstract

With the advance of nanotechnology, many new innovations for biomedical used have been publicly implemented. Gold nanoparticles have been developed and applied into wide variety of fields including in medical diagnosis. Thanks to its versatile surface which can be modified with many biological probes, specific detections can then be achieved. Either simple and quick detections or sophisticate but sensitive measurement can be established with these nanoparticles. เท this article, some distinct applications of colloidal gold particle as a latest diagnostic gadget, especially for DNA and protein detection, are summarized. These advantages propose a new promising medical diagnostic tool that is capable of clinical use in this nanomedicine era.
