Native-State Microscope could analyze tissue more effectively

Anaesthesiology

Researchers invented the native-state microscope that can scan large areas using fiber optics. It could allow for immediate, real-time microscopic confirmation of the complete removal of malignant tissues during surgery. In the not-so-distant future, surgeons could ensure the complete removal of malignant tumors, and pathologists could analyze tissue more efficiently, by using a device.

Osman said using conventional microscopes requires a few days of processing to produce an image. It also requires studying tissues that have been removed from the patient, which can make it challenging to pinpoint the exact location where they were removed if surgery is required later.

"For instance, a patient may undergo surgery to remove cancer," Osman said. "After the removed tissues are analyzed, the surgeon may determine that residual cancer still exists. The patient must then go through another procedure to remove it.

"The native-state microscope could be applied directly to the tissues during surgery to confirm that at a microscopic level, they have removed the malignancy, thus improving the effectiveness of these surgeries," he said. "The microscope incorporates a combination of fiber optics and direct laser treatment.

This allows for a two-in-one action of identifying residual malignant tissue within a large area and then eradicating it at a microscopic level. Osman said the microscope could also be used by pathologists during medical diagnoses. A native-state microscope eliminates the necessity of a physical biopsy by bringing the microscope directly to the diseased tissues.

The author took the next step to develop the native-state microscope is performing clinical trials that will optimize the device and harness its capacity.

A pathologist is then able to determine immediately whether the tissues are malignant or benign, allowing us to locate cancerous tissues and treat them on-site accurately. Osman disclosed the invention to the IU Office of Technology Commercialization, which protects, markets and licenses intellectual property developed at Indiana University so the industry can commercialize it.
