Numerical and experimental investigations of the formation process of ferrofluid droplets
This paper reports both experimental and numerical investigations of the formation process of ferrofluid droplets in a flow focusing configuration with and without an applied magnetic field. In the experiment, the homogenous ...
Magnetowetting and sliding motion of a sessile ferrofluid droplet in the presence of a permanent magnet
Motion of a droplet on a planar surface has applications in droplet-based lab on a chip technology. This paper reports the experimental results of the shape, contact angles, and motion of ferrofluid droplets driven by a ...
A tuneable micro-optofluidic biconvex lens with mathematically predictable focal length
Recent research efforts have been increasingly focused on the development of microlenses. Of great interest are in-plane optofluidic lenses due to the possibility of integrating them directly into a microfluidic network. ...
Formation and manipulation of ferrofluid droplets at a microfluidic T-junction
This paper reports the formation and manipulation of ferrofluid droplets at a microfluidic T-junction in the presence of a permanent magnetic field. A small circular permanent magnet with a diameter of 3 mm is used to ...
Generation and manipulation of monodispersed ferrofluid emulsions : the effect of a uniform magnetic field in flow-focusing and T-junction configurations
This paper demonstrates the use of magnetically controlled microfluidic devices to produce monodispersed ferrofluid emulsions. By applying a uniform magnetic field on flow-focusing and T-junction configurations, the size ...
Oxygen plasma treatment for reducing hydrophobicity of a sealed polydimethylsiloxane microchannel
Rapid prototyping of polydimethylsiloxane (PDMS) is often used to build microfluidic devices. However, the inherent hydrophobic nature of the material limits the use of PDMS in many applications. While different methods ...
