Current Research
Implantable Biosensors for in-vivo Monitoring of Glucose & Lactate Related to Trauma
Trauma that leads to hemorrhage results in poor peripheral perfusion, i.e., comprimised blood flow to the tissues, vasoconstriction, tissue hypoxia (depleted oxygen levels), hyperlactatemia (elevated lactic acid levels) and eventually hemorrhagic shock, a condition that results in multiple organ dysfunction syndrome (MODS). Our center is engaged in the development of the PSMBioChip (physiologic status monitoring biochip), an implantable biosensor system that can measure and remotely report on intramuscular or subcutaneous levels of lactate and glucose during hemorrhage. Present studies use a hemorrhage rat model and explore the development of the bioactive smart biorecognition layers for the biosensor, the integration of the miniaturized instrumentation, and the wireless communication between sensor and base station. Useful for severely injured soldiers and civilian trauma victims, this device promises to aid in the development of new resuscitation strategies.
Gene Expression Profiling of Primary Brain Tumors & Development of DNA Biochips
There are approximately 17,000 brain cancer victims in the United States each year. Current pathological methods for classifying the grades and stages of these tumors are subjective and prone to misdiagnosis. Experiments are being conducted using DNA microarrays to identify targeted suites of genes associated with astrocytomas. These genes will be used as probes in a brain tumor biochip. Such a chip will delineate that the World Health Organization has defined as classes of astrocytomas for improved diagnostics and will lead to imprived therapeutic efficacy. DNA biochips have the potential to revolutionize the way cancer tumors are classified and patients are stratified for targeted therapies.
Whole-Cell Neurotoxicity Biosensor as an Alternative to the Use of Animals
Cell-based neurotoxicity array biosensors increase testing throughput by providing multiple wells integrated with cell-based biosensing elements. By using an eight-well array system of differentiated neuronal cells, scientists can test for the effects of a toxin on eight differentiated cell cultures or eight toxins on a given cell culture. This platform project also offers researchers an alternative to using live animals in their investigations by providing differentiated cell cultures as proxies for living tissues.
