Stochastic Diffusion of Calcium Ions Through a Nanopore in the Cell Membrane Created by Electroporation
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 ... Read More
Simulation of Normal and Cancerous T-cell Membrane Electroporation
Electroporation is an increase of the cell membrane permeability due to the formation of aqueous pores in it when the cell is under the influence of an intense electric field [1][2]. The formation of such pores in the membrane can be used to enhance the uptake of chemotherapeutic drugs ... Read More
Simulations of Heat and Mass Transport During Biomass Conversion Processes Using 3D Biomass Particle Models with Realistic Morphology and Resolved Microstructure
Predictive simulations of biomass conversion processes will improve their technical performance and reduce economic uncertainty surrounding industrialization of biofuels production. The majority of present conversion simulations treat the biomass feedstock with simplifying assumptions ... Read More
Effect of a High Frequency Field on the Electric Double Layer Surrounding a Biomolecule in a Fluid
Biosensors based on silicon nanowires are of great interest for ultrasensitive biomolecular recognition of disease specific markers for early stage diagnosis [1]. However, there are limitations on the performance of these nanosensors in solutions at high ionic strength. This is because ... Read More
Photo-Biological Reactor for Organic Waste Consumption and Hydrogen Production
A simple steady-state photo-fermentative biochemical model was developed using the COMSOL Multiphysics'® Transport of Diluted Species physics interface. A dimensionless model seeks optimal physical parameters based on given biochemical parameters found in literature. A parametric sweep ... Read More
Solving Calcium Spatiotemporal Diffusion Using COMSOL Multiphysics® Software
This project involves a simplified biological problem that was used to test the potential of COMSOL Multiphysics® software for cardiac myocyte spatial modeling. We made several assumptions to simplify the biological complexity and to highlight the geometrical structures (i.e., lack of ... Read More
Biofluid-Structural Interaction in Abdominal Aortic Aneurysm for Predicting Timeline to Rupture: The Effect of Hypertension and Aorta Wall Material Properties
An abdominal aortic aneurysm (AAA) is a bulge formed in the large blood vessels that supply blood to the abdomen, pelvis, and legs. A fluid structure interaction model was developed in a 3D aortic aneurysm model, which was constructed from abdominal CT scan images. Combining medical ... Read More
Analysis of Heat Transfer in a Complex Three Dimensional Structure Fabricated by Additive Manufacturing
The goal of this study was to create a three dimensionally designed biomedical device with multiple functionalities and analyze its simulated heat transfer. The device would be fabricated through additive manufacturing; specifically electron beam melting (EBM). EBM has a feature size ... Read More
Simulation of Bio-medical Waveguide in Mechanical and Optical fields
This paper presents a freestanding waveguide to achieve the goal of detecting anastomosis leakage after colon surgery. The freestanding part is a thin membrane consisting of TiO2 rib and SiN ridge. This freestanding waveguide is designed both mechanically and optically to maintain ... Read More
Multiphysics Modeling of Electrode-Driven Renal Denervation for Hypertension Treatment
Introduction: Chronic arterial hypertension (HTN) is a pathological condition characterized by prolonged high level of arterial blood pressure causing major damages to several human body apparata. Renal sympathetic denervation (RDN) has been found to effectively reduce systemic blood ... Read More
