Patent number: 11466977Abstract: Since the fat content of pork is a deciding factor in grading the quality of meat, the use of a noninvasive subcutaneous probe for real-time, in situ monitoring of the fat components is of importance to vendors and other interested parties. Fortunately, in situ, in vivo monitoring of subcutaneous fat can be accomplished with spatially offset Raman spectroscopy (SORS) using a fiber-optic probe. The probe acquires Raman spectra as a function of spatial offset. These spectra are used to determine the relative composition of fat-to-skin. The Raman intensity ratio varies disproportionately depending on the fat content, with variations in slope that are correlated to the thickness of the fat layer. Ordinary least square (OLS) regression using two components indicates that depth-resolved SORS spectra reflect the relative thickness of the fat layer.Type: GrantFiled: March 18, 2021Date of Patent: October 11, 2022Assignee: Massachusetts Institute of TechnologyInventors: Peter T. C. So, Jeon Woong Kang, Hyung Min Kim

Publication number: 20210059582Abstract: Noninvasive glucose monitoring has been a long-standing need in diabetes management. Among many approaches to meeting this need, Raman spectroscopy has attracted attention due to its molecular specificity. Previous Raman-based glucose sensing can predict blood glucose concentration based on a statistical correlation between the reference glucose concentration and unspecified spectral features. However, the lack of glucose Raman peaks and non-prospective prediction have led to questions about the effectiveness of in vivo Raman spectroscopy for transcutaneous glucose sensing. Here, we disclose technology for directly observing distinct glucose Raman spectra from skin. The Raman signal intensities were proportional to the reference glucose concentrations in three live swine glucose clamping experiments. Tracking the spectral intensity based on the linearity enables prospective prediction with high accuracy in within-subject and inter-subject models.Type: ApplicationFiled: June 29, 2020Publication date: March 4, 2021Inventors: Jeon Woong Kang, Peter T.
