Silver nanoparticles are valuable in the field of plasmonics since silver has a higher field enhancement factor compared to other metals that possess plasmonic properties. The plasmonic properties of silver nanoparticles can be finely tuned to the incident light wavelength through their size, shape and dielectric environment, and they have long-term stability. In this work, an ultrathin polymer ...

Polymeric hydrogel is a promising class of drug delivery systems with the controlled release behavior in the body. In-situ forming hydrogels can be injected into the body as a fluid which forms a gel within the body tissue and improve the efficacy of the drugs. Various polymers have been used as in-situ hydrogel formulations. These polymeric formulations can form gels at body temperature while ...

Vein visualization systems such as the VeinViewer are vein-contrast enhancement devices that use an infrared camera to highlight blood or the underlying vasculature and project the image in real time onto the skin. Understanding the light propagation in a realistic skin model is critical, but only a few computational models have been developed to account for this particular system. We have ...

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 current therapies available to treat cancer patients are surgical operation and chemo therapy. The drawbacks are the side effects caused by these therapies. Hyperthermia is a treatment technique based on deactivation of cancer cells by raising the temperature in the range of 43 ºC and 48 ºC and has gained attention as an alternative therapy for cancer treatment. Iron oxide nanoparticles have ...

This paper utilizes COMSOL Multiphysics® software and the Application Builder to simulate neurological responses in nerve axons due to external electrical stimuli. The AC/DC Module of the COMSOL® software is first used to solve the Maxwell's equations. Then the results from the Maxwell's equations are used to drive a second model constructed using global equations using the Global ODE and DAE ...

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 ...

Mathematical skin models play an important role in fields such as transdermal drug delivery and assessment of dermal exposure to industrial chemicals. Extensive research has been conducted on modeling skin for transdermal drug delivery; however, little effort has been made to view the skin as a permeable layer to expel waste chemicals or toxins from the body. In this work, we focused on topical ...

Usually, when calculating the blood flow in cerebral arteries and intracranial aneurysms, blood is modeled as a Newtonian fluid, neglecting its shear-thinning behavior. Since flow diverting devices slow down the blood flow in the aneurysm sack, the accuracy of this assumption had to be reviewed. A Carreau Yasuda model is introduced as a non-Newtonian model for blood viscosity. CFD simulations of ...

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. The ...
