“…In the present work, carbon–Ag (C–Ag) nanocomposite thin films were deposited on a flexible substrate as part of the disposable stochastic sensor design. C–Ag nanocomposite thin films based on two materials (C = 99.98%, Ag = 99.9%) were prepared on A4 printing paper (commercially copy paper) using a cold plasma method, as described previously [ 20 , 21 ]. The same method was used to deposit a thin layer of Ag/AgCl (as reference electrode) and platinum (as auxiliary electrode) to provide the combined disposable 2D sensor ( Scheme 1 ).…”

Since the determination of the high toxicity of bisphenol A, alternative structures for bisphenols have been synthesized, resulting in bisphenols C, E, F, S, and Z. These bisphenols have replaced bisphenol A in plastic bottles, toys, and cans used for preserving food. Later, the toxicity and negative effects of all of these bisphenols on people’s health were proven. Therefore, there is a need for a fast ultrasensitive screening method that is able to detect the presence of these bisphenols in any condition directly from food samples. This paper presented a disposable device based on the utilization of a 2D disposable paper stochastic sensor for the fast ultrasensitive screening of food samples for bisphenols A, C, E, F, S, and Z. The 2D disposable sensor was obtained by the deposition of graphene and silver nanolayers on paper using cold plasma. Furthermore, the active side of the sensor was modified using 2,3,7,8,12,13,17,18-octaethyl-21H,23H Mn porphyrin. The limits of quantification of these bisphenols were 1 fmol L−1 for bisphenols C and E, 10 fmol L−1 for bisphenols A and F, 10 pmol L−1 for bisphenol S, and 1 pmol L−1 for bisphenol Z. The recoveries of these bisphenols in milk, canned fruits, vegetables, and fish were higher than 99.00% with RSD (%) values lower than 1.50%.

“…To date, many stochastic sensors have been proposed for screening certain diseases, assessing water quality, and determining certain pharmaceutically active ingredients. [11][12][13][14] In this work, we propose the use of a portable platform based on a sensor obtained by modifying a matrix comprising TiO 2 and reduced graphene oxide paste with calix [6]arene (C6A/TiO 2 / Fig. 1 The chemical structure of nonivamide.…”
