Different from traditional detection methods which were expensive and time consuming for biochemical analyses, a DNA chip assay by using gold nanoparticles (AuNPs) immunological amplification methods and radio frequency techniques was applied to detect DNA sequences rapidly and conveniently. First the capture DNA (cDNA) was immobilized to the substrate on which the LC shunt located. Then the target...
Aqueous gold nanoparticles (Au-NPs) without surfactant protection undergo irreversible aggregation upon a cryogenic treatment. However, a cryogenic process on aqueous gold nanoparticle solution containing tannic acid did not lead to nanoparticle aggregation. The tannic acid serves as surfactant to prevent aggregation of gold nanoparticles. In contrast, a reduction in the particle size in this solution...
Nanofluid is employed as working medium for conventional circular heat pipe. The nanofluid used in the present study is an aqueous solution of various-sized gold nanoparticles. The thermal resistance of heat pipe with nanofluid or with DI water was measured. The heat pipe was designed as a heat spreader for CPU in a notebook or a desktop PC. At a same charge volume, there is a significant reduction...
