FEAST of biosensors: Food, environmental and agricultural sensing technologies (FEAST) in North America. Biosens Bioelectron 2021; 178:113011. [PMID: 33517232 DOI: 10.1016/j.bios.2021.113011] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 01/04/2021] [Accepted: 01/16/2021] [Indexed: 02/08/2023]
Abstract
We review the challenges and opportunities for biosensor research in North America aimed to accelerate translational research. We call for platform approaches based on: i) tools that can support interoperability between food, environment and agriculture, ii) open-source tools for analytics, iii) algorithms used for data and information arbitrage, and iv) use-inspired sensor design. We summarize select mobile devices and phone-based biosensors that couple analytical systems with biosensors for improving decision support. Over 100 biosensors developed by labs in North America were analyzed, including lab-based and portable devices. The results of this literature review show that nearly one quarter of the manuscripts focused on fundamental platform development or material characterization. Among the biosensors analyzed for food (post-harvest) or environmental applications, most devices were based on optical transduction (whether a lab assay or portable device). Most biosensors for agricultural applications were based on electrochemical transduction and few utilized a mobile platform. Presently, the FEAST of biosensors has produced a wealth of opportunity but faces a famine of actionable information without a platform for analytics.

Weston M, Phan MAT, Arcot J, Chandrawati R. Anthocyanin-based sensors derived from food waste as an active use-by date indicator for milk. Food Chem 2020; 326:127017. [PMID: 32434111 DOI: 10.1016/j.foodchem.2020.127017] [Citation(s) in RCA: 37] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Revised: 05/07/2020] [Accepted: 05/07/2020] [Indexed: 12/23/2022]
Abstract
Active use-by date (AUBD) or freshness indicators hold great potential to reduce food waste. Herein, we develop an anthocyanin AUBD indicator that is capable of discriminating between fresh, spoiling, and spoiled milk. The sensor undergoes a visible blue to purple to pink color change in response to lactic acid, which is an indicator of microbial spoilage in milk. Anthocyanin is cast into a range of materials and the composite's suitability to monitor pH changes (pH 6.8 fresh milk vs pH 4.0 spoiled milk) is assessed. Of the materials studied, an anthocyanin-agarose film is nominated as the optimum materials with the best colorimetric performance. We introduce a new method to quantify anthocyanin color change by measuring red chromatic shift by digital analysis. The anthocyanin sensors will provide a real-time indication of actual milk quality, surpassing the function of traditional date marking tools that provide an indication of the expected shelf life.

[PMID: 31906350 PMCID: PMC7169468 DOI: 10.3390/diagnostics10010022] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Revised: 12/29/2019] [Accepted: 12/30/2019] [Indexed: 01/10/2023] Open
Abstract
In this manuscript, we discuss relevant socioeconomic factors for developing and implementing sensor analytic point solutions (SNAPS) as point-of-care tools to serve impoverished communities. The distinct economic, environmental, cultural, and ethical paradigms that affect economically disadvantaged users add complexity to the process of technology development and deployment beyond the science and engineering issues. We begin by contextualizing the environmental burden of disease in select low-income regions around the world, including environmental hazards at work, home, and the broader community environment, where SNAPS may be helpful in the prevention and mitigation of human exposure to harmful biological vectors and chemical agents. We offer examples of SNAPS designed for economically disadvantaged users, specifically for supporting decision-making in cases of tuberculosis (TB) infection and mercury exposure. We follow-up by discussing the economic challenges that are involved in the phased implementation of diagnostic tools in low-income markets and describe a micropayment-based systems-as-a-service approach (pay-a-penny-per-use—PAPPU), which may be catalytic for the adoption of low-end, low-margin, low-research, and the development SNAPS. Finally, we provide some insights into the social and ethical considerations for the assimilation of SNAPS to improve health outcomes in marginalized communities.
