Journal ArticleDOI
Thermocapillary actuation of droplets on chemically patterned surfaces by programmable microheater arrays
TL;DR: In this paper, a microfluidic device for the actuation of liquid droplets or continuous streams on a solid surface by means of integrated microheater arrays is presented.
Journal ArticleDOI
Microfluidic actuation by modulation of surface stresses
TL;DR: In this paper, the authors demonstrate the active manipulation of nanoliter liquid samples on the surface of a glass or silicon substrate by combining chemical surface patterning with electronically addressable microheater arrays.
Journal ArticleDOI
Planar digital nanoliter dispensing system based on thermocapillary actuation
TL;DR: The capability to dispense ultralow volumes onto a 2D substrate extends the functionality of microfluidic devices based on thermocapillary actuation previously shown effective in routing and mixing nanoliter liquid samples on glass or silicon substrates.
Journal ArticleDOI
Microfluidic detection and analysis by integration of thermocapillary actuation with a thin-film optical waveguide
TL;DR: In this paper, a planar thin-film waveguide is integrated with a microfluidic chip for directed surface flow, where microliter droplets are electronically transported and positioned over the waveguide surface by thermocapillary actuation, and attenuated intensity of propagating modes is used to detect droplet location, monitor dye concentration in aqueous solutions, and measure reaction rates with increasing surface temperature for a chromogenic biochemical assay.
Proceedings ArticleDOI
Thermocapillary actuation of liquids using patterned microheater arrays
TL;DR: In this article, a microfluidic actuation technique capable of directing nanoliter liquid samples on the surface of a glass substrate through the use of both electronically addressable heater arrays and chemical patterning was demonstrated.
