Intelligent non-colorimetric indicators for the perishable supply chain by non-wovens with photo-programmed thermal response

Abstract

High-performance and low-cost indicators are important in food and cosmetics industry but market uptake is low due to several challenges such as toxicity, cost and unclear reading. Here, the authors report on optically-programmed, non-colorimetric indicators based on nanotextured organic non-wovens, encoded by controlling their cross-linking degree.
