... Nowadays, metal oxides in the form of thick or thin films, which operate at elevated temperatures, ordinarily up to 400 • C, are widely used to design gas sensors of a chemiresistive type [1][2][3]. In order to reduce the working temperature and to advance the sensitivity, other materials are considered to meet the challenges of various current applications, including the Internet of Things [4]. Since the beginning of the XXI century, two-dimensional materials, primarily matured from a one atom-thick layer of carbon, called graphene [5], started to develop rapidly [1,6]. ...

... The World Health Organization (WHO) declared a public health emergency of international concern on 30 January 2020 and a pandemic on 11 March 2020. Since 2021, variants of the virus have emerged or become dominant in many countries with the Delta, Alpha, and Beta variants being the most virulent (Anaki & Sergay, 2021;Chen, et al., 2022;Lu, et al., 2022). At the present many countries have confirmed the high death rate, making COVID-19 one of the deadliest pandemics in history. ...
... The photographs of the fabricated MWCNT-, graphene-, and MWCNT/graphene hybridbased sensors are shown in Fig. 1a. In order to avoid excessive confinement of the sensing materials on the Ecoflex surface [7,25,26], the MWCNT and graphene are directly spray-coated on the sticky Ecoflex surface [27,28] and tested without encapsulation. Scanning electron microscopy (SEM) images of graphene and MWCNT coated on a glass substrate are shown in Additional file 1: Fig. S1a and S1b. ...

... Human orthopneumovirus, also called human respiratory syncytial virus (RSV), is a common respiratory virus that affects the lungs and respiratory tract, which can lead to hospitalization in severe cases. Importantly, it is the second largest pathogen that causes acute lower respiratory tract infection (ALRTI) deaths in infants and children under the age of 5 years (1). The global burden of virus-associated acute lower respiratory tract infections in 2019 linked RSV to 25.4 million to 44.6 million infections, 2.9 million to 4.6 million hospitalizations, and 15100 to 49100 deaths in hospitalized children under the age of 2 years (2). ...
... 31 Our study is consistent with several recent epidemiological studies that have reported an increased emergence and identification of aEPEC among EPEC infections, and there is an association with diarrheal outbreaks in both developing and developed countries. 30,[32][33][34][35][36][37][38] All strains in this study were positive for the EAST1 gene and negative for the stx gene ( Table 2). The EAST1 gene is originally recognized in strains of an enteroaggregative Escherichia coli (EAEC) isolated from a Chilean children's stool specimen while suffering diarrhea. ...
... In China, a nationwide Surveillance for Etiology of Respiratory Infections (SERI) program has been implemented by the Chinese Center for Disease Control and Prevention (China CDC) since 2009, testing a spectrum of common contagious pathogens causing acute respiratory infections (ARI) year round in 31 provinces [17]. A previous study based on SERI found that virus positive rates varied greatly across age groups and geographical regions [17]. ...
... Carbonaceous material and metals are commonly adopted as nanofillers integrated with a flexible substrate to act as strain/pressure sensors. For example, carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs) are two representative materials that have attracted extensive attention because of their outstanding properties and various forms [103]. Huang et al. demonstrated a wearable strain sensor based on multiwalled carbon nanotubes (MWCNT), which were encapsulated by PDMS to prevent the fragile conductive filler from stress-induced damage [104]. ...
... Salmonellosis has become a significant public health problem worldwide, causing approximately 115 million infections and 370,000 deaths globally [24]. From 2009-2018, The national-based prospective surveillance of all-ages patients with acute diarrhea showed that Escherichia coli and nontyphoidal Salmonella were the two leading bacterial pathogens in China [25]. Nontyphoidal Salmonella usually causes self-limiting gastroenteritis in humans and animals, while a few nontyphoidal Salmonella can also cause invasive nontyphoidal Salmonella (iNTS) life-threatened [26]. ...
