A novel class of micro pump was developed at the Biomagnetic Engineering Lab at Florida State University. The pump operates by utilizing the viscous effects that are dominant the micro scale and by spinning a [...]
Dielectrophoresis can be used to trap and position bioparticles efficiently and sucessfully in BioMEMS devices. This paper present a computational model to simulate this process. In particular, the model will solve for electric potential distribution, [...]
A novel fabrication of PMM(Polymethylmethacrylate) microneedle array using synchrotron radiation deep X-ray lithography is presented in this work. In general, microneedles with holes are required for biomedical application. The crown-shaped structure with quadruplets-microneedle is an [...]

In this paper, we report an amperometric-type enzymeless glucose sensor system based on nanoporous platinum (Pt) and platinum/platinum oxide (Pt/PtO) reference electrode, which are integrated with microfluidic chip. Glucose sensor employing no enzyme implies a [...]
Acute Myocardial Infarction (AMI), commonly referred to as a heart attack, is a disorder in which damage to an area of heart muscle occurs because of an inadequate supply of oxygen to that area leading [...]
An ultra-sensitive optical bionanosensor platform for integrin avb3 loaded human umbilical vein endothelial cells (HUVECs) was fabricated. The bionanosensor design involved the incorporation of an RGD (arginine-glycineaspartate) containing peptide conjugated BODIPY lipid soluble dye (donor) [...]
