New Findings on Biomedicine and Biomedical Engineering Described by Investigators at University of Toronto (Controlled ultrasonic micro-dissection of thin tissue sections)

By a News Reporter-Staff News Editor at Biotech Week -- Data detailed on Biotechnology have been presented. According to news originating from Toronto, Canada, by NewsRx correspondents, research stated, "In order to obtain sufficient quantities of pure populations of cells or a single cell from surrounding tissue for analytical investigation, we have developed an ultrasonic microdissection system. The system utilizes a vision-based method for detecting the contact between the microdissection needle tip and a target surface."

Our news journalists obtained a quote from the research from the University of Toronto, "A multilayer stack piezoelectric actuator is employed to generate ultrasonic vibrations for histological isolation. Automated micro-dissection is also realized using visual feedback and vision-based control. Experimental results on tumor tissue sections show that the system has a high dissection accuracy and efficiency and is able to realize dissecting arbitrary shapes in specified locations on a tissue sample."

According to the news editors, the research concluded: "Furthermore, effects in variations of vibration amplitude and frequency of ultrasonic micro-dissection as well as needle insertion depths on micro-dissection accuracy and speed were evaluated."
