“…The viruses were investigated in the concentration range of 1.1 Â 10 5 -1.1 Â 10 7 pfu mL À 1 with a detection limit of 1.1 Â 10 6 pfu mL À 1 for both viruses (Han et al, 2014). Other biosensors have been developed for other viruses based on antibody or DNA receptors including dengue virus NS1 protein (Dias et al, 2013), influenza virus type A DNA (Tam et al, 2009), feline calcivirus (Connelly et al, 2012), HIV-1 virus (Lee et al, 2013) and bacteriophage MS2 (Dantham et al, 2012). In our work, we achieved a detection limit of 8.08 Â 10 6 pfu mL À 1 with a real-time, cost-effective, reliable and reusable approach.…”

“…Efforts have been made to develop novel diagnosis methods for viruses, using techniques such as atomic force microscopy (Meillan et al, 2014), interferometry (Ymeti et al, 2007) and electrochemistry (Lee et al, 2013;Wei et al, 2013), or by implementing components such as carbon nanotubes (Dias et al, 2013;Tam et al, 2009), silicon nanowires (Svendsen et al, 2011), liquid crystals (Han et al, 2014), microcavities (Dantham et al, 2012) and microfluidics (Connelly et al, 2012;Matatagui et al, 2013) into sensor systems. Many of these studies, as well as others in the field, have used antibodies as the recognition material for virus detection exploiting the high specificity between an antibody and its analyte as a detection system (Bianco et al, 2013;Altintas et al, 2011).…”

“…Neglected tropical diseases (NTDs) are a category of infectious diseases that are inextricably linked to poverty that thrive in tropical and subtropical regions (Dias et al, 2013;Linares et al, 2013). Among the NTDs, dengue virus (DV) is of particular importance and is considered one of the major public health problems in 112 countries (Gurugama et al, 2010).…”

“…O teste que representa o equilíbrio entre especificidade e custo é o de detecção de antígenos NS1 (13,42), sendo este o foco desta dissertação. Sua identificação se encontra como o teste mais indicado para o diagnóstico laboratorial da dengue (15).…”

“…Como a concentração atingida no sangue pode ser considerada alta, este torna-se um alvo relativamente fácil de se detectar, ainda mais se considerado o ponto de vista clínico, onde o interesse reside no diagnóstico baseado na presença ou ausência da proteína, caso em que a concentração perde a relevância, embora a sensibilidade das plataformas encontradas na literatura apresentem um queda significativa ao se tratar de infecções secundárias, de modo que a busca por dispositivos com um limite de detecção menor é de grande interesse (13,51), ainda mais levando-se em consideração a chance de incidência de DHF nestes casos. Sua detecção é comum na forma do teste ELISA ou na forma de imunossensores, sendo esta última o foco do próximo capítulo.…”
