Paper Abstract

One of the In-vivo system's challenge is real time display the sensing information. Usually Ultrasound, CT, MRI, PET are used to get the internal information, this thesis proposed another approach to address the display challenge. Special nano-particles are in-taken or injected to living subject (usually into blood circulation) to sense and collect psychological information when the active particles pass through the tissues of interest. Using the wound healing mechanism, these activated particles (Information collected) can be drifted out to the wound area and adhibited close to the skin, then skin can show different color if the activated particles are concentrated enough in the specific area to create a skin screen. The skin screen can display the blood status, internal organ's temperature, pressure depending the nano-particles' function and their pathway. This approach can also be used to display in-body video if the particles are sensitive and selective enough. In the future, the skin screen can be bio-computer's monitor. The wound healing in an animal model normally divides in four phase: Hemostasis, Inflammation, Proliferation and Maturation. Hemostasis phase is to form a stable clot sealing the damaged vessel. Inflammation phase causes the blood vessels to become leaky releasing plasma and PMN’s (polymorphonucleocytes) into the surrounding tissue and provide the first line of defense against infection. Proliferation phase involves replacement of dermal tissues and sometimes subdermal tissues in deeper wounds as well as contraction of the wound. Maturation phase remodels the dermal tissues mainly by fibroblast to produce greater tensile strength. The skin screen wound will be carefully controlled to be triggered at dermis layer.
