Three dimensional mathematical models are developed to simulate the blood flows in patient specific right coronary arteries with two stenoses. Simulations are carried out with various flow parameters under physiological conditions. Both Newtonian and non-Newtonian blood viscosity models ... En savoir plus
Organ-on-a-chip microdevices combine microfluidics, MEMS, and biotechnology techniques to mimic the multicellular architectures, tissue-tissue interfaces, physicochemical microenvironments, and vascular perfusion of the body.[1] Such devices are being developed to provide better levels ...

The analyzed MEMS oscillator is composed by a spring (beam) supported mass that needs to vibrate with a high Q-factor in the horizontal plane. Nevertheless, the transverse motion needs to be highly damped (low Q-factor). The purpose of the work was to explore different system ... En savoir plus
In a first approach towards application of the magnetic frequency mixing technique to microfluidic structures, microplanar coils have to be designed along with sample reservoir. For this, a COMSOL Multiphysics® electrical model along with an analytical calculation is used in order to ... En savoir plus
The thermocapillary effect is widely used in microfluidic applications for sensing and actuation and can also be used to generate rigid-body motion. Furthermore, it is possible to cast Marangoni flows to achieve controllable rigid-body motion in 3D space. To this effect, here we present ... En savoir plus
Acoustic standing waves can be used to manipulate micrometer sized particles, cells and organisms. In most applications these objects are driven towards pressure nodal lines, predominantly by the primary acoustic radiation force. Interestingly, at intermediate particle concentrations, ...

Micro-sized separation devices are in a state of research globally due to its simplicity; cost effectiveness and high precision for analyzing biological and medical samples, e.g. blood cells. Magnetophoresis is a technique to separate cells on biochip by manipulating the magnetic ... En savoir plus
The main focus of the present study is the parametric investigation of the influence of viscosity on breakup dynamics of the non-Newtonian sodium carboxymethylcellulose (CMC) droplets. It presents the numerical simulations of the fluid dynamics of CMC droplets with shear-thinning ... En savoir plus
With the progress of immunosensing technology, the detection of diseases at early stages is feasible using surface based heterogeneous immunosensors [1]. Literature contains few reports where it is verified that reaction spot of smaller size leads to high fractional occupancy of targets, ... En savoir plus
A magnetic colloid, also known as a ferrofluid, is a colloidal suspension of single-domain magnetic particles with typical dimensions of about 10nm, dispersed in a liquid carrier. Since the 1960, when these materials were initially synthesized, their technological applications are ... En savoir plus
