Designing Biomaterials Using Mussel Adhesive Chemistry, Bruce P. Lee
Designing Biomaterials Using Mussel Adhesive Chemistry, Bruce P. Lee
TechTalks
Marine mussels secrete adhesive proteins that enable them to anchor to surfaces under water. We are exploiting chemistry utilized by mussels to design bioadhesives for tissue repair and wound healing, smart biomaterials for on-demand antipathogenic applications, and smart adhesives that can be turned on and off with externally applied stimuli.

TechTalks
From the perspective of biomechanics, my research is multidisciplinary, bridging the gap between physiology/biology and quantitative sciences. Currently, the applications are on cancer detection and differentiation, therapeutic monitoring, staging liver fibrosis, risk assessment of aneurysm rupture, and more.

Implantable Sensors For Regenerative Medicine, Keat Ghee Ong
TechTalks
In vivo, real-time measurement of local environmental parameters such as strain, pressure, temperature, pH, oxygen tension and specific biomarkers can be valuable for regenerative medicine research and therapies. Wireless implantable sensors are an attractive approach for certain regenerative medicine applications due to its relative simplicity and low cost. Presented here are such two implantable sensors. The first sensor is based on a miniature wireless sensor network that can digitize physical and chemical parameters and continuously stream measurements to a nearby receiver via a 2-way communication protocol. With the incorporation of a strain gauge, this sensor platform was applied to record …

Biodegradable Zinc Vascular Implant Materials, Jeremy Goldman
TechTalks
Bioabsorbable metal stents are being developed to mitigate the long-term side effects associated with corrosion-resistant stents. A decade-long research with iron (Fe)- and magnesium (Mg)-based stent materials has concluded with little success. Fe produces a voluminous, retained oxide product in the arterial wall, whereas Mg and its alloys corrode too rapidly. A breakthrough in the field of biodegradable metallic stents was made in 2013 in our research team (Drs. Goldman – Biomedical Engineering and Drelich – Materials Science and Engineering) with the introduction of zinc (Zn) and its alloys, which are free of the flaws observed for Fe- and Mg-based …

Stem Cell And Tissue Engineering Research, Feng Zhao
TechTalks
My research focuses on stem cell and tissue engineering. By combining stem cell biology and engineering tools, the Zhao Lab seeks strategies to biofabricate completely biological tissues to regenerate or repair damaged tissues or organs. The function of engineered tissues is being strengthened by recapitulating the in vivo environment of natural tissues. The underlying mechanism is being explored through investigating the interaction of cells with environmental factors such as topographical cues, biophysical forces, and oxygen tensions. We also prompt stem cell research at Michigan Tech to meet the progress and advance of the outside scientific society. Training opportunities are consistently …
Point-Of-Care Microfluidic Device For Blood Typing, Hector Moncada-Hernandez
Point-Of-Care Microfluidic Device For Blood Typing, Hector Moncada-Hernandez
TechTalks
There has been increasing efforts to translate laboratory blood tests analysis into portable, reliable, and cheap miniaturized devices. Electrokinetic-based microfluidic devices provide a new approach to blood tests with a simple infrastructure for the manipulation of cells. Previous studies show red blood cells’ (RBC) dielectrophoretic response changes based on the different ABO-Rh antigens present in the cells membrane. In this research, an alternate-current electric signal with a frequency sweep (0.1 – 1 MHz) is applied through an array of electrodes to generate non-uniform electric fields and induce dielectrophoretic forces on RBC from all eight blood types. The RBC’s response to …
