The acid-disassociation of surface groups generates the surface charge that drives fundamental nanoscale ion transport behaviors, such as ion current rectification in nanopores. Ion current rectification can be utilized for high sensitivity label-free sensors. The disassociation of ... En savoir plus
Microfluidics and Biosensors are two principal fields that paved the way for the inception of Lab-on-a-chip (LOC) which provides early and cost-effective disease detection, from monitoring to treatment. LOC is a device that uses very small amounts of fluid on a microchip to do certain ... En savoir plus
Transdermal drug delivery is an emerging mechanism for continuous systematic solutions in medical healthcare problem. Transdermal drug delivery has significant advantages when compared to conventional methods such as oral administration or intramuscular injection. Most of the ... En savoir plus
Packed bed microreactors (PBMR) and ferrofluids are independently enormously used in a broad range of applications in the healthcare sector. In a PBMR, one of the primary factors for controlling the reaction rate is the bed porosity which immediately affects the catalyst distribution and ... En savoir plus
Recent events underscore the importance of rapid diagnostic tests for detecting viruses such as the SARS-CoV-2 coronavirus or for screening cancer biomarkers. Many fluidic-based diagnostics applications require careful control of chemical and biological species concentrations. In this ... En savoir plus
This work reports how an EWOD-driven micropump is simulated using COMSOL Multiphysics®. Electrowetting-on-Dielectrics (EWOD) is frequently used technique to manipulate liquids on small scales. With the help of the EWOD effect and the use of topological optimized tesla valves, a pump can ... En savoir plus
Currently in the semiconductor industry more than 80% of silicon crystal are grown by the Czochralski (Cz) method. In this method, fused silica (SiO2) crucibles and graphite heaters are used inside furnaces. The surface of the crucibles, which are in contact with the molten silicon, is ... En savoir plus
The mechanical characterization of certain cell types is important to obtain physiological insights. For instance, tumor and normal cells can be distinguished by elasticity, indicated by the amount of deformation under given stress. Simulations help to understand, verify and improve the ...

In the field of coding and industrial marking areas, CIJ technology is based on high speed emission of ink drops (20 m/s) which are directed onto a moving printing medium. The printing quality depends, on one hand, on drops position on the media determined by the drop charge and the ... En savoir plus
Electroporation is the process of creating temporary hydrophilic pores in the cell membrane by applying an external electric field of specific strength and duration. It is used for gene transfection, and transport of other useful biomolecules and therapeutic drugs into the cell. When a ... En savoir plus
