Acoustic-Mechanic Modeling of Polydimethylsiloxane in the MHz Regime for Metamaterials Applications
Polydimethylsiloxane (PDMS) is a biocompatible material widely used in biomedical applications such as implantable sensors. A realistic modeling of PDMS in acoustic-mechanic simulation is useful especially for medical applications which use ultrasonic waves as interrogation source. ... En savoir plus
Ionic Neuromodulation and Neurosensing Platform for In Vitro Studies
Overview We successfully simulated a template iontronic system for closed-loop neuromodulation and neurosensing. The model’s goal is to support the careful design of novel platforms for in-vitro micro-electrode-array sensors coupled to conductive polymer-based (CP) ionic actuators used ... En savoir plus
Modeling of Oxygen Metabolism in 3D Cell Constructs with LiveLink™ for MATLAB®
In silico models can be exploited to predict cellular dynamics, such as resource uptake, migration and proliferation. Continuum modelling strategies such as finite element (FE) simulations are amongst the most common, but cannot exhaustively describe the metabolic consumption of cells, ... En savoir plus
Multiphysics Inertial Particle Focusing (IFP) Model Validated for 3D Microfluidic Geometries
Inertial focusing of particles in a fluid flow is a physical effect induced by inertial forces already happening at the micro-fluidic scale. COMSOL Multiphysics® has provided an implementation of the drag and lift forces to compute this effect for a constant parallel-wall fluid channel ... En savoir plus
3-D Modeling of Light, Flow, Mass and Heat Transfer in Coral Colonies
Corals are symbiotic marine organisms greatly dependent on the dynamic gradients of light, temperature and chemical species, all affected by the water flow in their surroundings. We developed a multiphysics modelling approach to simulate the microscale spatial distribution of light, ... En savoir plus
Electrochemical Impedance Spectroscopy in Carbonate Buffered Media for Biosensing Applications
Electrochemical Impedance Spectroscopy (EIS) is a technique commonly used to investigate the properties of the electrode surface and the bulk electrolyte in an electrochemical cell [1]. An AC excitation signal is applied with a frequency range, typically from 0.01 Hz to 1 MHz, and the ... En savoir plus
Modeling the Indoor Removal of Volatile Organic Compounds (VOCs) by Botanical Biofiltration
Historically, indoor air quality (IAQ) has received less attention than outdoors, although people spend >90% of their time in the indoor environment. A major group of indoor air pollutants is volatile organic compounds (VOCs), which are detrimental to human health even at low ... En savoir plus
Optimization of the Oxygen Supply in Dynamic Cell Cultures
In many medical and biotechnological applications, cells are grown in dynamic cell cultures. Usually, the cells are cultivated on a scaffold with a complex channel structure through which the nutrient fluid flows and into which the cells can grow. However, a known problem is that the ...

Electrothermoplasmonic Flow in Gold Nanoparticle Suspensions
Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient leads to a strong electrothermal flow that can be used for multiple purposes. Combining simulations and ... En savoir plus
Numerical Simulation-Driven Design of Nanophotonic Biosensors
Optical biosensors are powerful analytical tools for detecting and quantifying biological molecules and particles with high sensitivity and specificity. These devices operate on the principle of detecting changes in optical signals. For example, surface plasmon resonance (SPR) biosensors ... En savoir plus
