NC1194: Nanotechnology and Biosensors
(Multistate Research Project)
NC1194: Nanotechnology and Biosensors
Duration: 10/01/2016 to 09/30/2021
Statement of Issues and Justification
Development of sensing and processing technologies utilizing nanotechnology has become more relevant for furthering our understanding of biological phenomena related to food, agriculture, environment, and energy. As we understand the molecular mechanisms that underlie the emergence and spread of pathogens and their consequent impact on our agricultural and food systems, and gain insight into the molecular mechanism of life itself, it becomes clear that the technology to investigate, intervene and mitigate need to be correspondingly small, i.e. within the realm of nanotechnology.
According to the FY 2014-2018 Strategic Plan published by the USDA, one of the strategic goals for this period is to “Ensure that all of America's children have access to safe, nutritious and balanced meals.” Within this goal, Specific Objective 4.3 states that we must “Protect public health by ensuring that food is safe”. Reduction in the number of foodborne illnesses will require a comprehensive "farm-to-fork" risk assessment, coupled with appropriate technological measures to screen, identify, and eliminate offending food pathogens.
In addition to safety concerns in processed foods, plant/animal pathogens also represent major threats to worldwide food security. Rapid responses to crops and livestock epidemics require fast and accurate evaluation of plant/animal pathogens, which also calls for advances in biosensor technology to provide more user-friendly tools and techniques. Besides pathogen detection, novel biosensors could support better and more rapid monitoring of crop growth and animal welfare, which could lead to better practice of production/processing that will help safeguard both food security and environmental sustainability in the long term.
Related, Current and Previous Work
Nanotechnology and biosensors may present a double-edged sword to the food and agricultural systems. On one hand, they hold great promise to improve life quality (e.g., Wu et al. 2005; Elliott and Zhang 2001; Kim et al. 2004; Cao et al. 2005; Waychunas et al. 2005, Diallo et al. 1999; Fujishima et al. 2000; Long and Yang 2001; Yue and Economy 2005, Kong et al. 2000; Cui et al. 2001; Nicewarner-Pena et al. 2001). On the other hand, nanotechnology may present health and contamination risks to the ecosystems because they introduce new materials to the environment (e.g., Dreher 2004; Halford 2004; Renwick et al. 2004). Despite the rapid development of these technologies recently, there are still knowledge gaps in how to properly apply nanotechnology and biosensors to the agricultural systems.

MethodsMultidisciplinary experimentation and modeling methods at different scales will be used to fulfill the objectives. We will use bench-scale and field-scale experimentation and modeling methods to investigate the application and implication of nanotechnology in agricultural and biological systems. These methods can be summarized as: 1. Bench-scale Investigation: Laboratory experiments will be conducted to synthesis and characterize, and explore the applications of various types of nano-based materials. Mathematical modeling will be developed and model simulations will be used to help the data analysis. 2. Field-scale Investigation: Field-scale experiments will be used to evaluate the applicaiton and impact of nanotechnology to agriculture and the environment. Mathematical models will be used to help the data analysis.

Projected ParticipationView Appendix E: Participation
The general educational goal of the NC-1194 committee is to provide a framework for biosensor and bionanotechnology education to a broad audience of agriculture and food science students outside the traditional research community (physical science/engineering graduate students) that is supported by and integrated into the educational and outreach goals of our departments and institutions. We firmly believe that undergraduates will benefit from such an education, even those who will not pursue a scientific career. These students will be the backbone of our future workforce who may be responsible for handling agricultural products and/or food safety issues.
Nanotechnology is continuing to have a profound impact over our society, by bringing new technical breakthroughs in material and biological, and by creating new environmental and ethical challenges related to its implementation in many biological applications. To manage these complex issues, we will need future generations to understand the technology in order to make educated decisions concerning its use. Courses on modern biosensors and nanotechnology are not widely available for agricultural and food sciences students in today's college curriculum, the NC-1194 committee on nantechnology and biosensors is uniquely positioned to address these educational needs and serve our students' best interests.
To achieve these goals, the committee will: 1. Implement a course-material sharing mechanism (firstly through file-sharing on dropbox, then a website to be developed) to share teaching materials. McLamore from University of Florida will lead this effort. Available materials to be shared inlcude Biosensors and nanotechnology course materials developed at MSU, Univ. of Arizona, Univ. f Florida, ISU, Purdue and University of Hawaii. New teaching materials will be shared as they are developed at participating institutes. By generating this common hub for teaching materials, we believe our students will be greatly benefited as they can gain access to a much broader range of learning materials beyond their own institution. 2. Utilize the open-bioinstrumentation potentiostat approach to facilitate student learning. Jenkins from Univ. of Hawaii and Bhalerao from Univ. of Illinois are developing a general purpose data acquisition and control system which he expects to be fully functional for Fall 2016 term. The potentiostat will be supported by an interface through an Android app over Bluetooth to make it super flexible for graphical data presentation, manipulation and sharing. All committee members will be able to utilize this approach in our lab courses to enrich student learning, and to encourage team-work and networking between students from different institutions. This would be a priority item on the committee’s action list to be implemented in 2017, and throughout the duration of this project.
One aspect of nanotechnology that is of particular interests to the general public is the potential impact of nanomaterials to human, animal and environmental health. The work of the committee can be further improved by including such expertise as nanosafety and security. We will actively seek to recruit experts in these fields to join our team. This will be a priority item on our action list for 2016-2017.
NC-1194 is organized according to the guidelines in the USDA Multistate Research Manual, as found at http://www.wisc.edu/ncra/regionalmanual.doc. Membership includes an administrative advisor (Dr. Vincent Bralts), a CSREES representative (Dr. Hongda Chen) and project leaders from cooperating stations. Meetings are held annually. The secretary for the coming year is elected at the end of each meeting. The previous secretary moves up to vice-chair and the vice-chair to chair. These three officers, the past chair, and the administrative advisor constitute the executive committee. The dates of the annual meeting (typically two or three days) are determined by the host and the chair after consulting the Committee at the preceding meeting. The chair develops an agenda for the upcoming meeting in consultation with the executive committee and feedback from the membership. The annual meeting includes technical reports from each represented station, discussion of results and future areas of collaboration, and meetings among smaller ad hoc committees. The location of the meeting for the coming year is determined by vote at the end of each meeting. Meetings are typically held in conjunction with annual meeting of a related professional organization. Minutes are prepared by the secretary and sent to members. An annual report is prepared by the chair, submitted to the administrative advisor, and posted at the NC-1194 web site.
