DESCRIPTION (provided by applicant): Breast cancer is the most common cancer among women in the United States and is second only to lung cancer as a cause of cancer-related death. Much of the reduced mortality over the past decade can be attributed to early detection and timely medical intervention. Mammography remains the gold standard for breast cancer screening and early detection. Despite its higher initial cost, digital mammography is rapidly becoming the modality of choice, because of its speed, automation and archiving capability. Image quality, however, remains arguably no better than that achieved on older analog systems. We propose a technological innovation that will enhance the quality of digital mammographic images: a stationary anti-scatter grid with high primary transmission and very low scatter-to- primary ratio that will increase image contrast and, thus, facilitate interpretation of the resulting image. Creatv's grid is the result of two technical innovations: a novel, high precision lithographic technique that is superior to conventional x-ray and UV methods, and a proprietary replication technique suitable for high volume production of metal microstructures. The grid can be manufactured at competitive cost and made broadly available to mammography system makers and users. The improvement in image quality will allow radiologists and computer-aided software to make more correct interpretation of the images, leading to a reduced number of false positives and false negatives and saving lives.

DESCRIPTION (provided by applicant): We propose a novel technology for detection of low abundance protein in body fluids, with initial application to a mental health biomarker. One of the most significant challenges facing biomarker discovery is the need t o separate high and low abundance proteins for detection of the latter more easily and with precision. The proposed technology is a novel chromatography platform that utilizes unique functionalized micro-structures to capture and purify target analytes fro m clinical tissue specimens. It does not utilize conventional beads, filters or magnets. We believe that the proposed method will stand out as is a potential breakthrough in the field of sample preparation and will be applied to analysis of numerous low ab undance biomarkers. For validation of the proposed technology, this technology will be applied to the detection of neuronal biomarkers. In Phase I of this SBIR, we plan to recover human neurofilament proteins from serum. Because of their specific localizat ion in the central nervous system, the presence of neurofilament proteins outside of this compartment may indicate damage and/or disease of the central nervous system. The presence of neurofilament proteins in body fluids can serve as a sensitive indicator of central nervous system diseases, including multiple sclerosis, Parkinson's disease and HIV dementia. This Phase I SBIR will demonstrate the proof-of-principle detection of neurofilaments as the target analyte in the proposed chromatography technology a nd design an automated instrument to be constructed in Phase II. PUBLIC HEALTH RELEVANCE: We propose to develop a novel technology for detection of low abundance protein in body fluids, with initial application to a mental health biomarker called n eurofilaments. Because of their specific localization in the central nervous system, the presence of neurofilament proteins outside this compartment may indicate damage and/or disease of the central nervous system. The presence of neurofilament proteins in body fluids can serve as a sensitive indicator of central nervous system diseases, including multiple sclerosis, Parkinson's disease and HIV dementia.

Micro- and nanofilters have a wide range of applications in many fields, including medical diagnostics, drug delivery, medical implants, and hemodialysis. Some issues that limit commercial application of current nanofilters in medicine are low pore density, non-uniform pore size, and the use of materials that are not biocompatible. A method is described to fabricate high porosity polymer and diamond micro- and nanofilters producing smooth, uniform and straight pores of high aspect ratio. Pore size, density, and shape can be predetermined with a high degree of precision by masks and controlled etch. The method combines energetic neutral atom beam lithography and a mask. This technology allows etching polymeric materials in a clean, well-controlled, and charge-free environment, making it very suitable for fabricating nanofilters and other components for biomedical applications.

A method of detecting target cells and pathogens in a test sample concentrates to target cells in solution by filtering or capturing the target cells on a solid support. The target cells are tagged with a fluorescent dye and dispersed in a solution or suspension. The resulting solution or suspension are introduced to a fluorometer to specifically identify and quantitate the target cells. The target cells can be lysed or whole when introduced to the fluorometer.

A new sensitive cell biomarker of solid tumors is identified in blood. This biomarker can be used to determine presence of carcinomas, rapid determination of treatment response, early detection of cancer, early detection of cancer recurrence, and may be used to determine therapy.
