eDentin- a tissue engineered reparative dentin

Summary Current dental restoration materials trigger immune responses and poorly replicate the natural structure of the tooth, which delays the healing process. The current technology is a novel biomaterial that more closely mimics natural dentin and thereby allows for more efficient healing of the tooth. Technology Overview Cement-based materials...

Postprocessing algorithms to minimize fixed pattern artifact and reduce trigger jitter in swept source OCT

Summary OHSU developed post-processing algorithms which could minimize fixed pattern artifact and reduce trigger jitter in swept source optical coherence tomography (SS-OCT). Technology Overview Swept-source OCT has advantages of less fringe washout and faster imaging speeds compared to conventional spectraldomain detection. Therefore, it is attractive...

Retinomorphic Sensors

This sensor, intended for use in computer vision applications, only produces a signal in response to changes in light conditions. Background Inspired by the way retinal cells respond to light, retinomorphic sensors are hoped to enable faster identification of moving objects than software-based approaches. Unlike conventional optical sensors, such...

Label-free microfluidic device for cancer liquid biopsy

Summary Liquid biopsies offer a less invasive method of early cancer detection; however, circulating cancer cells are rare and difficult to detect. The current technology is a device that allows for sensitive, label-free enrichment of circulating neoplastic cells in order to facilitate the detection of cancer biomarkers from peripheral blood samples. Technology...
