Development Of An Enzymatic Glucose Biosensor For Applications In Wearable Sweat-Based Sensing, Allison Anne Cargill Jan 2016

Development Of An Enzymatic Glucose Biosensor For Applications In Wearable Sweat-Based Sensing, Allison Anne Cargill

Graduate Theses and Dissertations

The recent development and commercial availability of wearable devices like the FITBIT® and Apple Watch® reflect an increasing consumer interest in actively monitoring health parameters. Though wearable devices are beginning to emerge in a variety of fields and applications, there is particular interest in the development of wearable monitors for continuously sensing blood glucose levels. Diabetes currently affects nearly 10% of the American population, a number that is expected to rise in the near future, prompting increased interest in noninvasive methods of monitoring glucose levels. This interest in noninvasive monitoring and the recent advent of continuous monitoring products ...


Passive Micromixers And Organic Electrochemical Transistors For Biosensor Applications, Senaka Krishna Kanakamedala Oct 2011

Passive Micromixers And Organic Electrochemical Transistors For Biosensor Applications, Senaka Krishna Kanakamedala

Doctoral Dissertations

Fluid handling at the microscale has greatly affected different fields such as biomedical, pharmaceutical, biochemical engineering and environmental monitoring due to its reduced reagent consumption, portability, high throughput, lower hardware cost and shorter analysis time compared to large devices. The challenges associated with mixing of fluids in microscale enabled us in designing, simulating, fabricating and characterizing various micromixers on silicon and flexible polyester substrates. The mixing efficiency was evaluated by injecting the fluids through the two inlets and collecting the sample at outlet. The images collected from the microscope were analyzed, and the absorbance of the color product at the ...


Microbiorobots For Single Cell Manipulation, Mahmut Selman Sakar Nov 2010

Microbiorobots For Single Cell Manipulation, Mahmut Selman Sakar

Publicly Accessible Penn Dissertations

One of the great challenges in nano and micro scale science and engineering is the independent manipulation of biological cells and small man-made objects with active sensing. For such biomedical applications as single cell manipulation, telemetry, and localized targeted delivery of chemicals, it is important to fabricate microstructures that can be powered and controlled without a tether in fluidic environments. These microstructures can be used to develop microrobots that have the potential to make existing therapeutic and diagnostic procedures less invasive.

Actuation can be realized using various different organic and inorganic methods. Previous studies explored different forms of actuation and ...
