Numerical Modelling of a Sinusoidal Grating-Based Surface Plasmon Coupled Emission Biosensor

Sukhotskiy V., Cady N.C., Reddy I.V.A.K., Furlani E.P., University at Buffalo (SUNY), US

We present a full-wave computational model to study the optical behavior of a versatile sinusoidal grating-based surface plasmon-coupled emission (SPCE) biosensor. Surface plasmons (SPs) are coherent oscillations of conduction electrons on a metal surface excited [...]

Giant Enhancement of the Chiro-Optic Response of Chiral Plasmonic Media using Structured Light

Reddy I.V.A.K., Sukhotskiy V., Baev A., Furlani E.P., Prasad P.N., Haus J.W., University at Buffalo (SUNY), US

We propose an approach to achieve a great enhancement and broad spectral tunability of the chiro-optic response of plasmonic metasurfaces by exploiting their interaction with light of complex polarization, endowed with both spin (SAM) and [...]

Analytical Modeling of Microfluidic Cantilever Sensor with Evaporating Ethanol

Marepalli L.K., Sukhotskiy V., K. Reddy I.V.A., Verma A., Furlani E.P., University at Buffalo, US

Resonating microcantilevers are widely used for myriad biochemical sensing applications. Small samples can be characterized for their physical [1], chemical [2], and thermal [3] properties. An example of such a sensor is shown in Fig. [...]

Numerical Simulation of Pulsed Electromagnetic Field Tissue Therapy

Sukhotskiy V., Marepalli L.K., Verma A., Fournier J., Gellman G., Bacon W., Furlani E.P., University at Buffalo, US

Applications of pulsed electromagnetic field (PEMF) therapy have grown steadily over the last 50 years, as clinical evidence of effectiveness for various treatments, e.g. pain relief, bone and tissue (wound) healing etc., has emerged [1]. [...]

Numerical Simulation of Extrusion Additive Manufacturing: Fused Deposition Modeling

Verma A., Sukhotskiy V., Vishnoi V. Amiri Roodan P., Furlani E.P., University at Buffalo, US

We demonstrate a 3D computational fluid dynamic (CFD) simulation of the Fused Deposition Modeling (FDM) process. Extrusion-based additive manufacturing technologies, such as FDM, are advancing rapidly as applications of rapid prototyping for finished product development [...]

Magnetohydrodynamic Drop-on-Demand Droplet Formation and Coalescence

Sukhotskiy V., Karampelas I.H., Vishnoi P., Vader S., Vader Z., Vader S., Vader Z., Amiri Roodan V., Verma A., Garg G., Furlani E.P., University at Buffalo, US

In recent years there has been a meteoric rise in interest and research in the field of metal additive manufacturing in both academia and industry. Such processes represent an attractive alternative to more traditional metal [...]

Additive Manufacturing of Microfluidic Components via Wax Extrusion

Schneider P., Sukhotskiy V., Christie L., Siskar T., Karampelas I.H., Furlani E.P., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Fused deposition modelling (FDM) has been extensively applied in the fields of rapid prototyping and 3D printing, but typically this technique has mostly been used for the fabrication of low melting point plastics. This paper [...]

Self-Assembly and Optical Behavior of Magnetic-Plasmonic Nanostructures

Liu K., Xue X., Sukhotskiy V., Furlani E.P., University at Buffalo, US

We introduce a bottom-up method for the fabrication of nanostructured photonic media and demonstrate proof-of-principle using a multiphysics modeling approach. The method involves magnetic field-directed self-assembly of magnetic-plasmonic core-shell particles (e.g. Fe3O4@Au) into extended particle [...]

Drop-on-Demand 3D Metal Printing

Karampelas I.H., Vader S., Vader Z., Vader S., Vader Z., Sukhotskiy V., Verma A., Garg G., Tong M., Furlani E.P., University at Buffalo, US

At present, most 3D metal printing applications involve metal powder sintering or melting under the influence of an external energy source such as a laser (e.g. Selective Laser Sintering (SLS) and Direct Metal Sintering (DMLS) [...]

Computational Analysis of Electrical Stimulation Devices to Promote Wound Healing

Anand A., Liu K., Sukhotskiy V., Verma A., Fournier J., Gellman G., Bacon W., Furlani E.P., University at Buffalo, Garwood Medical Devices, LLC, US

The treatment of wounds is a fundamental and major challenge in health care. Chronic wounds (e.g. diabetic) are particularly problematic and pervasive, afflicting approximately 6 million patients in the US alone at an annual cost [...]
