Methods For Enhancing Expression Of Secondary Cell Wall Cellulose Synthases In Plants, Chandrashekhar P. Joshi

Michigan Tech Patents

Described are methods for making transgenic plants capable of expressing secondary cell wall cellulose synthases and methods of enhancing expression of secondary cell wall cellulose synthases in plants. Also described are plants produced by the methods. Plants comprising at least three exogenous polynucleotides encoding secondary cell wall cellulose synthases are also provided.

Fabrication Of Biocompatible, Vibrational Magnetoelastic Materials For Controlling Cellular Adhesion, Hal Holmes, Ee Lim Tan, Keat Ghee Ong, Rupak Rajachar

Michigan Tech Publications

This paper describes the functionalization of magnetoelastic (ME) materials with Parylene-C coating to improve the surface reactivity to cellular response. Previous study has demonstrated that vibrating ME materials were capable of modulating cellular adhesion when activated by an externally applied AC magnetic field. However, since ME materials are not inherently biocompatible, surface modifications are needed for their implementation in biological settings. Here, the long-term stability of the ME material in an aqueous and biological environment is achieved by chemical-vapor deposition of a conformal Parylene-C layer, and further functionalized by methods of oxygen plasma etching and protein adsorption. In vitro cytotoxicity …

Alternating Current Dielectrophoretic Manipulation Of Erythrocytes In Medical Microdevice Technology, Kaela M. Leonard

Dissertations, Master's Theses and Master's Reports - Open

Medical microdevices have gained popularity in the past few decades because they allow the medical laboratory to be taken out into the field and for disease diagnostics to happen with a smaller sample volume, at a lower cost and much faster. Blood is the human body's most readily available and informative diagnostic fluid because of the wealth of information it provides about the body's general health including enzymatic, proteomic and immunological states. The purpose of this project is to optimize operating conditions and study ABO-Rh erythrocytes dielectrophoretic responses to alternating current electric signals. The end goal of this project is …
