hCps://engineering.purdue.edu/MSE/People/ptProfile?id=11440; hCps://engineering.purdue.edu/~allebach/ hCps://engineering.purdue.edu/~gchiu/ Sensing and biosensing have become increasingly relevant for the prevenQon of food-­‐borne illnesses through the detecQon food-­‐borne pathogens. However, challenges related to the manufacturing capabiliQes and pracQcality of widespread use of such sensors has prevented biosensor manufacturing and commercializaQon on a large scale. The goal of this project is to integrate roll-­‐to-­‐roll manufacturing of cellulose films with inkjet prinQng technologies and nanofuncQonalizaQon into a reliable and scalable nanomanufacturing plaWorm. Specifically, we will orient these nanomanufacturing technologies towards the fabricaQon of single-­‐use, reliable, stable, and high-­‐throughput pathogen nanobiosensing test strips that will be usable for food safety monitoring. Within the Purdue College of Engineering, this project is led by a mulQdisciplinary team of Purdue faculty members (Jan Allebach, George Chiu, Lia Stanciu) and will provide advanced cross-­‐disciplinary training for graduate students in manufacturing, materials engineering, microbiology, food safety and environmental monitoring. It is being conducted in partnership with Professors Lisa Mauer and Amanda Deering in the Center for Food Safety Engineering, and will make extensive use of faciliQes in the Birck Nanotechnology Center in Research Park that have been developed for research in scalable nanomanufacturing, based on roll-­‐to-­‐roll prinQng technologies •

Towards an in-­‐line Monitoring of Pathogenic Bacteria on Food Surface via non-­‐contact Op9cal Metrology : Please No9ce: Professor Arun K.

To address global food safety and food security, we propose to invesQgate the feasibility of using non-­‐invasive and non-­‐contact opQcal and thermal metrologies to provide the presence of micro-­‐organisms on the food surface. First elasQc light scaCer (ELS) method will be invesQgated on the food surface. Since all the light will scaCer off from both bacteria and food surface it is criQcal to address the signal to noise raQo (SNR) with given wavelength of interrogaQng laser. • 
Second method is using infrared thermography. Since all living organisms employ respiraQon for survival and metabolize substrates for energy, the resulQng temperature gradient between the organisms and the background could be used as a foot print for microbial detecQon. • 
At least two graduate students, one working in developing instrumenta9on with engineering emphasis and one with microbiology knowledge in pathogen detec9on from various food matrices would be essen9al. •

This study will focus on basic and applied research on low-­‐power, inexpensive, wireless sensors for food security, bio-­‐medical, and industrial applicaQons. No commercial sensors exist today that simultaneously saQsfy all requirements for such applicaQons. The student in this program will likely receive training in most of the before men9oned areas and will work under the supervision of appropriate faculty at Purdue University.

The funcQon of packaging is to protect the food in the package in order to maintain its quality, stability and overall integrity. The package should protect from exchange of chemicals, gases and moisture that can trigger physical, chemical and microbiological changes.

Of parQcular importance this group’s experQse focuses on the physical changes to powdered materials and products that cause caking, agglomeraQon and phase transformaQons. Only Ques9ons about Scholarship Applica9on: • 
This would include not only exchange with the environment but also the potenQal toxicity that could arise from migraQon of nanoparQcles embedded in the packaging film; how the film mechanical response and surface interacQons (interfaces) are affected with environmental condiQons.

We have developed a label-­‐free method of pathogen detecQon, using chips paCerned with molecular recogniQon ligands and a Fourier-­‐based readout method. High-­‐affinity ligands are prepared by organic synthesis or isolated as natural products, and modified for opQmal presentaQon and paCerning using inkjet prinQng technologies. The detecQon strategy has the potenQal for further development into handheld sensors, for use in hospitals, public arenas, or in limited-­‐resource seongs.
