Journal ArticleDOI
Carbon Nanotube Matrix for Highly Sensitive Biosensors To Detect Pancreatic Cancer Biomarker CA19-9
Anshu Thapa,Anshu Thapa,Andrey Soares,Juliana C. Soares,Iram T. Awan,Diogo Volpati,Matias Eliseo Melendez,José Humberto Tavares Guerreiro Fregnani,André Lopes Carvalho,Osvaldo N. Oliveira +9 more
TL;DR: A thin film sensing unit on interdigitated gold electrodes combining polyethyleneimine and carbon nanotubes in a layer by layer fashion, onto which antibodies anti-CA19-9 were adsorbed with a supporting layer of N-hydroxysuccinimide and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide solution to detect pancreatic cancer biomarker.
Journal ArticleDOI
Nanostructured polypyrrole powder: a structural and morphological characterization
Edgar A. Sanches,Scarlat F. Alves,Juliana C. Soares,Arnaldo Machado da Silva,Cristina Gomes da Silva,Sérgio Michielon de Souza,H.O. Frota +6 more
TL;DR: In this article, a polypyrrole powder was chemically synthesized using ferric chloride (FeCl3) and characterized by X-ray diffraction (XRD), Le Bail Method, Fourier Transform Infrared Spectrometry (FTIR), and Scanning Electron Microscopy (SEM).
Journal ArticleDOI
Detection of the Prostate Cancer Biomarker PCA3 with Electrochemical and Impedance-Based Biosensors.
Juliana C. Soares,Juliana C. Soares,Andrey Soares,Andrey Soares,Valquiria da Cruz Rodrigues,Matias Eliseo Melendez,Alexandre Cesar Santos,Eliney Ferreira Faria,Rui Manuel Reis,André Lopes Carvalho,Osvaldo N. Oliveira +10 more
TL;DR: This study presents the first electrochemical and impedance-based biosensors that are capable of detecting PCA3 down to 0.128 nmol/L and could distinguish between cell lines expressing the endogenousPCA3 long non-coding RNA from cells that did not contain detectable levels of this biomarker.
Journal ArticleDOI
Structural characterization of Chloride Salt of conducting polyaniline obtained by XRD, SAXD, SAXS and SEM
Edgar A. Sanches,Juliana C. Soares,Ana Carolina Mafud,Edson G. R. Fernandes,Fabio L. Leite,Fabio L. Leite,Yvonne Primerano Mascarenhas +6 more
TL;DR: In this article, the emeraldine-salt polyaniline form (ES-PANI) was chemically synthesized using hydrochloric acid at time synthesis ranging from 0.5 to 48h and characterized by X-ray diffraction (XRD), LeBail fit, Small-angle X-Ray Diffraction (SAXD), Smallangle Xray Scattering, SAXS and Scanning Electron Microscopy (SEM).
Journal ArticleDOI
Adsorption according to the Langmuir-Freundlich model is the detection mechanism of the antigen p53 for early diagnosis of cancer.
