This vortex acts like a centrifuge to isolate specific types of particles in the circulating liquid. Particle concentrations replicate the size, location and shape of the infrared laser pattern.<\/p>\n<p>Stuart Williams, also a Purdue engineering professor and co-author, says the technology two types of applications. &#8220;The first is micro- and nanomanufacturing and the second is lab-on-a-chip sensors,&#8221; says Williams. &#8220;The latter has demonstrated biologically relevant applications in the past couple of years, and its expansion in this field is immediate and ongoing.&#8221;<\/p>\n<p>Williams believes the technology is ready for some applications, including medical diagnostics and environmental samples.
