This invention provides a simple and rapid method for measuring pesticide and/or antibiotic penetration into plants and produce. The method involves the use of surface-enhanced Raman scattering (SERS) mapping for in situ and real-time tracking of the analytes by using metallic nanoparticles as probes.

Many medical patients are now able to directly access their electronic health records (EHR). Providing such direct access has been shown to lead to improved healthcare outcomes through the patient’s enhanced understanding of their medical conditions and treatment. However, EHR contain medical jargon that challenge populations with lower health literacy. Low health literacy is associated with several negative health outcomes, including failure to follow up on doctor’s orders and repeat health problems.

 

ComprehENotes is the first ever tool that helps clinicians assess the health literacy of their patients with regard to EHR, identifying areas of weakness that they need to work to improve with their patients. The tool is test comprising a series of multiple choice questions that assess patients’ understanding across six major health conditions: cancer, COPD, diabetes, heart failure, hypertension, and liver failure. The questions were administered to hundreds of respondents, and natural language processing was used to evaluate and verify the effectiveness of the questions in gauging patient comprehension.

This invention provides a new and low-cost substrate system and related methods for highly sensitive detection of analytes in a gaseous phase or multiphase sample medium.

Zeolites have found wide application in catalysis and separation processes due to their tunable pore structure and active sites, and they show remarkable stability in commercial use. Recently, ultra-thin two-dimensional (2D) zeolite nanosheets have been synthesized from zeolite precursors. These ultra-thin nanosheets show promise for high throughput separations and catalytic reactions involving bulky molecules. A commercially feasible synthesis method, however, has yet to be developed. State-of-the-art methods require high energy input and multiple processing steps, and give low yield and small nanosheet size.

 

Professors Winter and Fan have developed a simpler, lower energy method to synthesize ultra-thin 2D zeolite nanosheets from precursor zeolite materials, such as MCM-22 and ml-MFI. In the method, zeolite precusors can be subjected to either a short sonication or chaotic flow treatment in the presence of commercially available telechelic polymers, resulting in exfoliated zeolite nanosheets. While demonstrated in batch, this process can potentially be scaled and made continuous.

This invention provides cost-effective, dual-functional substrates for analyte detection by using Surface Enhanced Raman Spectroscopy (SERS) and Surface Enhanced Infrared Absorption Spectroscopy (SEIRAS).

This invention provides a rapid and sensitive method for the detection of bacteria in food matrices and water. The method integrates the sensitive surface-enhanced Raman Scattering (SERS) technique and the advanced Raman mapping technique to identify and quantify bacteria.
