Journal ArticleDOI
Cross-stream migration and coalescence of droplets in a microchannel co-flow using magnetophoresis
TL;DR: In this article, the authors studied the mechanism of cross-stream migration and the coalescence of aqueous droplets flowing in an oil-based ferrofluid with a co-flowing aouous stream in the presence of a magnetic field and revealed that the migration phenomenon is governed by the advection and magnetophoretic (τm) time scales.
Journal ArticleDOI
Dynamics of a Water Droplet over a Sessile Oil Droplet: Compound Droplets Satisfying a Neumann Condition
TL;DR: The dynamics of compound droplets with a denser liquid (water) droplet over a less dense sessile droplet (mineral oil) that satisfies the Neumann condition and coalescence of water droplets of size above and below critical size at the axisymmetric position are reported.
Journal ArticleDOI
A microsystem for extraction, capture and detection of E-Coli O157:H7
TL;DR: Use of the microsystem for detection of pathogenic bacteria extracted directly from the soil sample has been demonstrated and Variation of fluorescence with concentration of bacteria in the sample is studied.
Journal ArticleDOI
Understanding of the role of dilution on evaporative deposition patterns of blood droplets over hydrophilic and hydrophobic substrates.
TL;DR: The study unravels the interesting attributes about one of the important physico-chemical factors that affect the evaporation of blood droplets and the resulting deposition patterns on substrates with different hydrophobicity.
Journal ArticleDOI
Self-Transport and Manipulation of Aqueous Droplets on Oil-Submerged Diverging Groove.
TL;DR: The study reveals that complete engulfment of aqueous droplets in the oil layer, that is attributed to a positive spreading parameter ( S > 0), is a prerequisite for the droplet transport.
