Comprehensive studies of drug transport in nanofibres based mats have been performed to predict drug release kinetics. The paper presents our approach to analyze the impact of fibers arrangement, one of the parameters varied in our parallel experimental studies. COMSOL Multiphysics® has been used to assess the impact of the various purposed arrangements of fibers within the mat. Drug release ...

Retinitis Pigmentosa (RP) and Age-related Macular Degeneration (AMD) are diseases causing blindness in a large number of people. In this type of degenerative disease, mostly the photoreceptors are damaged. Thus attempts have been made to electrically stimulate the surviving inner retinal neurons and retinal ganglion cells (RGC) in order to restore vision. In this paper, the electrode-tissue ...

Vibration and music therapies are non-invasive treatments having effective results although their basics are still disputed. By the application of COMSOL Multiphysics® software for modeling and analysis, some of the nonlinear physical phenomena laying on these applications may be clarified. Acoustic environmental stimuli at different intensities are continuously interacting with our bodies, ...

During peripheral intravascular interventions one of the main issues is the correct deployment of the guidewire (GW) to the anatomical site which has to be treated, often supported by a microcatheter. There is a trade-off between the microcatheter flexibility and its push-ability to be able to reach the anatomical site. The catheter design has been defined with 2 transition zones. A parametric ...

The aim of present work is to present and calibrate a new mechanistic model that includes physical and biokinetic processes to reproduce the algae growth in photobioreactor or ponds during long-term scenarios. A COMSOL Multiphysics® model is used to implement the microalgae processes mainly based on River Water Quality Model 1 (RWQM1) (Reichert et al., 2011). The main innovation of the model is ...

Study of neurons plays a key role in the fields of basic and medical research aiming at the development of electrically active implants. The Fitzhugh-Nagumo equations are used to model and simulate the spike generation and propagation in a squid giant axon using COMSOL Multiphysics® 3.5a Software. It is shown that the Fitzhugh-Nagumo equations allow for a geometrical explanation of important ...

This paper describes the design of an ultrasonic transducer using different lead free piezo-electric materials and evaluates their performance with different glucose levels in the human blood. COMSOL Multiphysics 4.2a was used for the simulation study using 2D axis symmetric model of piezoelectric transducer which was designed with lead free piezoelectric materials such as Barium Sodium Niobate ...

We simulated the diffusion of calcium ions through a nanopore created in the cell membrane by electroporation, in presence and absence of the external electric field responsible of the membrane permeabilization. First we solved the set of coupled differential equations that describe the process of ionic diffusion in a 2D nanopore model using the AC/DC Module and the Transport of Diluted Species ...

This project utilizes the heat transfer module of the COMSOL Multiphysics environment to model the effects that an ohmic heating probe will have on neural tissue. The model quantifies the thermal impact of active components embedded on a neural micro probe by solving the Penne’s bioheat equation with an external MATLAB function to determine the heat generation along the length of the probe. ...

In using DEP for particle manipulation, researchers often use a formula to calculate the DEP forces in which the forces are proportional to the particle radius to the third power. This formula assumes that the electrical field, E, will not be affected by the presence of a particle, no matter what the actual size and the dielectric property of the particle are. This work confirms that the ...
