“…Other research has been conducted to further investigate the capabilities of graphene for use in biosensors such as nonfunctionalized graphene biosensors, 3D microstructure biosensors, and even microfuidic chemiresistive biosensors. All have found that the graphene has allowed for precise bacterial detection on or in mediums such as saliva, tooth enamel, various biological tissues, and biomedical equipment [86][87][88][89][90].…”

Graphene-based materials have been shown to have advantageous properties in biomedical and dental applications due to their high mechanical, physiochemical, antibacterial, and stem cell differentiating properties. Although graphene-based materials have displayed appropriate biocompatible properties when used in implant materials for orthopedic applications, little research has been performed to specifically test the biocompatibility of graphene for dental applications. The oral environment, compared to the body, varies greatly and must be considered when evaluating biocompatibility requirements for dental applications. This review will discuss in vitro and in vivo studies that assess graphene’s cytotoxicity, antibacterial properties, and cell differentiation ability to evaluate the overall biocompatibility of graphene-based materials for dental applications. Particle shape, size, and concentration were found to be major factors that affected overall biocompatibility of graphene.

There is a constant need to maintain the quality of consumed food. In retrospect to the recent pandemic and other food-related problems, scientists have focused on the numbers of microorganisms that are present in different food items. As a result of changes in certain environmental factors such as temperature and humidity, there is a constant risk for the growth of harmful microorganisms, such as bacteria and fungi, in consumed food. This questions the edibility of the food items, and constant monitoring to avoid food poisoning-related diseases is required. Among the different nanomaterials used to develop sensors to detect microorganisms, graphene has been one of the primary materials due to its exceptional electromechanical properties. Graphene sensors are able to detect microorganisms in both a composite and non-composite manner, due to their excellent electrochemical characteristics such as their high aspect ratios, excellent charge transfer capacity and high electron mobility. The paper depicts the fabrication of some of these graphene-based sensors, and their utilization to detect bacteria, fungi and other microorganisms that are present in very small amounts in different food items. In addition to the classified manner of the graphene-based sensors, this paper also depicts some of the challenges that exist in current scenarios, and their possible remedies.

“…O elemento biológico pode ser uma biomolécula, uma enzima, anticorpos ou até mesmo um organismo. O transdutor, por seu lado, pode ser ótico, quimiorresistivo, eletroquímico ou piezoelétrico [12][13][14][15][16][17][18][19]. Os biossensores possuem vantagens imediatas, tais como resultados rápidos e seletividade; nos últimos anos as suas sensibilidade e especificidade evoluíram de forma significativa criando novas estratégias para a modificação de superfície tendo em vista a amplificação de sinal na deteção de diferentes biomoléculas [20].…”
