“…In order to be able to use them, it is necessary that these circuits are properly packaged. Their packaging usually provides a variety of functions [ 10 , 11 , 12 , 13 ], such as protection from environmental factors, as any chemical changes may reduce the efficiency of the circuit, as well as mechanical strength and heat management both to increase the reliability and service life of the circuit and to prevent material damage [ 14 ]. The circuit also needs to be interconnected with the packaging to enable its interaction with a user, another circuit, or a larger system.…”

In pipeline production, there is a considerable distance between the moment when the operation principle of a biosensor will be verified in the laboratory until the moment when it can be used in real conditions. This distance is often covered by an optimization and packaging process. This article described the packaging and optimization of a SARS-CoV-2 biosensor, as well as the packaging of its electronic readout circuit. The biosensor was packed with a photosensitive tape, which forms a protective layer and is patterned in a way to form a well in the sensing area. The well is meant to limit the liquid diffusion, thereby reducing the measurement error. Subsequently, a connector between the biosensor and its readout circuit was designed and 3D-printed, ensuring the continuous and easy reading of the biosensor. In the last step, a three-dimensional case was designed and printed, thus protecting the circuit from any damage, and allowing its operation in real conditions.

“…Standard expiration dates are a quick and accurate way to predict the food quality, but they do not account for food spoilage from packaging damages. Therefore, using sensing devices in place of destructive, time-consuming, and expensive analytical tools to evaluate the state of the food prior to purchase or consumption, is the ideal method to guarantee food quality and safety [4,5].…”

Smart packaging of food products is a new promising technology aiming to the preservation of consumer’s health and safety while prolonging the products’ self-life in transport and mass storage. Smart packaging can be applied by using chemical and/or biological sensors for monitoring indicators associated with bacterial growth and spoilage, as well as pathogen contamination. Poultry meat is a nutrient-rich matrix which supports the growth of various micro-organisms and the extended storage time can allow the proliferation of different microbial species on meat surfaces. The nature of the packaging approaches and storage factors can dictate the nature of the spoilage that transpires, with respect to the dominant microflora of the end-product. In the present study an innovative approach is explored for the development of cost-effective 3D-printed biosensors for monitoring known indicators associated with bacterial growth and spoilage in poultry meat. Spoilage was also independently measured using MSI and FT-IR spectroscopic methods. The development of a protocol for pathogen screening was also investigated with real-time polymerase chain reactions (qPCR).
