[Article] Study of gold nanoparticles and live cells by Chia-Wei Lee, En-Hong Lin, Ji-Yen Cheng, Pei-Kuen Wei

By Chia-Wei Lee, En-Hong Lin, Ji-Yen Cheng, Pei-Kuen Wei

We current a planar evanescent wave PEW method mixed with part distinction optical microscopy to check the interactions among cells and gold nanoparticles AuNPs. The PEW technique employs a dual-fiber-line consultant to couple mild right into a skinny glass slide. It produces a uniform and lengthy evanescent wave close to the glass floor, as established by way of the optical near-field size. Highcontrast AuNP pictures are acquired through the PEW illumination. while, cells are saw in basic terms through the use of the section distinction microscopy. The nanoparticles and phone pictures indicated that unmodified AuNPs had no interactions with cells, very likely as a result of unfavourable floor fees on either cells and nanoparticles. The electrostatic proposal was once additional proven by way of coating AuNPs with certainly charged poly L-lysine. DNA aptamers for floor mucin glycoprotein have been lined on AuNPs to illustrate the appliance for unmarried nano particle monitoring.
