Manipulating colloids with mobile nanotweezers

17 января, 2018 - 17:56
Researchers have merged two important technologies of nanomanipulation - plasmonic tweezers and magnetically driven microbots - in order to overcome their individual limitations and achieve new functionalities that did not exist before. This technique is applicable to different types of particles in various fluids. The resulting mobile nanotweezers' performance combines the best of both worlds: capturing, maneuvering, and positioning sub micrometer objects of various materials at low illumination intensities, high speeds, and with great control.

Nanofluidics - recent progress

16 января, 2018 - 17:24
Nanofluidics is the study and application of fluids in and around geometries with nanoscale characteristic dimensions. The field of nanofluidics is not brand-new. Some issues associated with nanoscale fluidics have been occasionally dealt with by researchers in membrane science, colloid science, and chemical engineering for many decades. A recent review article provides a selected overview of the recent progress, rather than a comprehensive review of the entire field.
