“…); the strain of the viruses; the loss of viral viability in the drying process after application of the solutions containing it to the surfaces before the exposure times and in virus recovery; and to environmental factors such as solar incidence, RH and temperature. In addition, a lack of standardized methods for this kind of test may also be a reasonable cause of data heterogeneity (Mihucz et al, 2022), which makes it difficult for one to compare the results from different studies. However, some tendencies may still be verified, such as the propensity of lower persistence periods of the SARS-CoV-2 onto porous surfaces as discussed earlier.…”

Health authorities such as the World Health Organization and the US Centers for Disease Control and Prevention state that while SARS-CoV-2 contamination from surfaces such as food or its packaging is possible, it is not seen as the primary way of contagion. In studies addressing virus survival on surfaces, the virus is no longer detected on porous objects such as corrugated cardboard and fabric after 2 and 5 days, respectively, and also on non-porous surfaces such as plastic and stainless steel for periods longer than 7 days. It was also observed that this persistence depends on environmental factors such as temperature, relative humidity and solar radiation incidence. The Coronavirus Disease-2019 (Covid-19) pandemic also had an impact on food industries, whereby digitalization trends increased, as well as the packaging industry with the expansion of e-commerce, consumer demand for packaging that is easy to disinfect and the development of more environmentally responsible packaging. On the other hand, taking into account the fear of contamination by the virus, consumers felt safer handling disposable products or single-use packaging instead of reusable packaging, which goes against the progressive ban on disposable packaging in regions, such as the European Union (EU). In the post-pandemic, concerns regarding the usage of plastics will be resumed, and in the long term, a reduction in the use of single-use packaging and a growth in recyclable waste generation rates similar to those predicted before Covid-19 is expected.

This paper presents a sponge-based electrochemical sensor for rapid, on-site collection and analysis of infectious viruses on solid surfaces. The device utilizes a conducting porous sponge modified with graphene, graphene oxide, and specific antibodies. The sponge serves as a hydrophilic porous electrode capable of liquid collection and electrochemical measurements. The device operation involves spraying an aqueous solution on a target surface, swiping the misted surface using the sponge, discharging an electrolyte solution with a simple finger press, and performing in situ incubation and electrochemical measurements. By leveraging the water-absorbing ability of the biofunctionalized conducting sponge, the sensor can effectively collect and quantify virus particles from the surface. The portability of the device is enhanced by introducing a push-release feature that dispenses the liquid electrolyte from a miniature reservoir onto the sensor surface. This reservoir has sharp edges to rupture a liquid sealing film with a finger press. The ability of the device to sample and quantify viral particles is demonstrated by using influenza A virus as the model. The sensor provided a calculated limit of detection of 0.4 TCID50/mL for H1N1 virus, along with a practical concentration range from 1−10 6 TCID50/mL. Additionally, it achieves a 15% collection efficiency from single-run swiping on a tabletop surface. This versatile device allows for convenient on-site virus detection within minutes, eliminating the need for sample pretreatment and simplifying the entire sample collecting and measuring process. This device presents significant potential for rapid virus detection on solid surfaces.
