Carbon nanotubes for electrochemical biosensing
Gustavo A. Rivas,María Dolores Rubianes,Marcela C. Rodríguez,Nancy F. Ferreyra,Guillermina L. Luque,María L. Pedano,Silvia A Miscoria,Concepción Parrado +7 more
TL;DR: The aim of this review is to summarize the most relevant contributions in the development of electrochemical (bio)sensors based on carbon nanotubes in the last years.
Journal ArticleDOI
Carbon nanotubes paste electrode
TL;DR: In this article, the performance of carbon nanotubes paste electrodes (CNTPE) prepared by dispersion of multi-wall carbon Nanotubes (MWNT) within mineral oil is described.
Journal ArticleDOI
Peptide Nucleic Acid Probes for Sequence-Specific DNA Biosensors
Joseph Wang,Emil Paleček,Peter E. Nielsen,Gustavo A. Rivas,Xiaohua Cai,Haruki Shiraishi,Narasaiah Dontha,and Denbai Luo,Percio A. M. Farias +8 more
TL;DR: PNA recognition layers thus offer significant advantages for sequence-specific DNA biosensors, compared to their DNA counterparts, including significantly higher sensitivity and specificity, faster hybridization at room and elevated temperatures, minimal dependence on ionic strength, and use of shorter probes.
Journal ArticleDOI
DNA electrochemical biosensor for the detection of short DNA sequences related to the human immunodeficiency virus.
Joseph Wang,Xiaohua Cai,Gustavo A. Rivas,Haruki Shiraishi,Percio A. M. Farias,Narasaiah Dontha +5 more
TL;DR: An electrochemical biosensor for the detection of short DNA sequences related to the human immunodeficiency virus type 1 (HIV-1) and the direct adsorptive chronopotentiometric stripping measurements of trace levels of various HIV-1 DNAs are reported.
Journal ArticleDOI
DNA electrochemical biosensors for environmental monitoring. A review
J. Wang,Gustavo A. Rivas,Xiaohua Cai,Emil Paleček,Peter E. Nielsen,Haruki Shiraishi,Narasaiah Dontha,Denbei Luo,Concepción Parrado,Manuel Chicharro,Percio A. M. Farias,Florenda S. Valera,Douglas H. Grant,Mehmet Ozsoz,M.N. Flair +14 more
TL;DR: This review describes recent efforts aimed at coupling nucleic acid recognition layers with electrochemical transducers, and considers DNA hybridization sensors for sequences related to microbial or viral pathogens, and DNA-modified carbon electrodes for monitoring low molecular weight priority pollutants interacting with the surfaceconfined DNA.
