Publication number: 20200399589Abstract: A collagen-fibronectin-based method enables the production of tumors of centimeter size with recognizable pathological traits. The method supports reproducing tumor heterogeneity with preinvasive and invasive phenotypes and stacking of tumor portions using a paper-scaffold with 80 ?m-punched holes for larger nodule creation and easy separation of tumor portions for analysis. Macrotumors are convenient for testing drug delivery and therapeutic tools that necessitate a minimum tumor size relevant to in vivo.Type: ApplicationFiled: June 9, 2020Publication date: December 24, 2020Applicant: Purdue Research FoundationInventors: Sophie Andree Lelievre, Rahim Rahimi, Tim Kwok

Patent number: 10772560Abstract: A wearable paper-based platform with simultaneous passive and active feedback for monitoring perspiration is provided. The sensor platform comprises two modules: a disposable wicking-based sweat collection patch with discrete colorimetric feedback, and a reusable electronic detachable module for active feedback. The disposable patch comprises a hygroscopic wicking material laminated between two polymeric films. The wicking material is patterned with a radial finger design that offers discretized visual readout of the sensor. The active module attaches to the film and alerts the user when the film collects a pre-determined volume of sweat. The multi-feedback system allows high-performance athletes who value objective quantification of perspiration to better assess their sweat loss during physical activities.Type: GrantFiled: October 2, 2017Date of Patent: September 15, 2020Assignee: Purdue Research FoundationInventors: Babak Ziaie, Manuel P. Ochoa, Vaibhav Jain, Rahim Rahimi
