Monodispersive FePt magnetic nanoparticles with hydrophobic ligand were chemically synthesized and with controllable surface-functional properties. In order to compare and select the high saturation magnetization of FePt nanoparticles, the synthesized solvents were changed to effectively increase magnetization due to the increased particle size and isolated distance of each nanoparticles. The surface...
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...
The current real-time PCR (polymerase chain reaction) platforms, which can detect and quantify several target DNA simultaneously, are equipped with discrete optics and detectors for different fluorescence wavelengths. However, the optical loss, due to the different lengths of the channels for several dyes, lowers the performance of fluorescence detection. Especially on the PCR platforms of lab-on-a-chip...
Different from traditional detection methods including polymerase chain reaction (PCR) based assays and enzyme-linked immunosorbent assays (ELISA) which are expensive and time consuming for biochemical analysis, in our study, a DNA chip assay using gold nanoparticle (AuNP) immunological amplification method and RFID communication platform were applied to detect DNA sequences rapidly and conveniently...
