Portable Microalgal Biosensor for Herbicide Monitoring
(Wiley, 2019-02)
The need for in-situ and real-time tools to monitor the fate ofpesticides in extensive areas is of great concern to preserve theenvironment in countries where agroindustry represents anessential part of its economy. In ...
Developing a novel paper-based enzymatic biosensor assisted by digital image processing and first-order multivariate calibration for rapid determination of nitrate in food samples
(Royal Society of Chemistry, 2018-06)
For the first time, a novel analytical method based on a paper based enzymatic biosensor assisted by digital image processing and first-order multivariate calibration has been reported for rapid determination of nitrate ...
How low does the oxygen concentration go within a sandwich-type amperometric biosensor?
(Elsevier Science Sa, 2012-11)
Software for the automatic non-linear least squares fit of chronoamperometric responses corresponding to sandwich-type amperometric biosensors has been developed. The so-called Simplex algorithm computes a minimum value ...
Recent advances in the development of electrochemical hydrogen peroxide carbon nanotube–based (bio)sensors
(Elsevier, 2019-03)
The relevance of H2O2 as biomarker for different neurodegenerative diseases and cancer has been one of the most significant incentives for the development of new (bio)sensors that allow a more sensitive, selective, fast, ...
Development of Electrochemical Sensors/Biosensors to Detect Natural and Synthetic Compounds Related to Agroalimentary, Environmental and Health Systems in Argentina: A Review of the Last Decade
(Multidisciplinary Digital Publishing Institute, 2021-11)
Electrochemical sensors and biosensors are analytical tools, which are in continuous development with the aim of generating new analytical devices which are more reliable, cheaper, faster, sensitive, selective, and robust ...
Electrochemical biosensors for the determination of toxic substances related to food safety developed in south America: Mycotoxins and herbicides
(MDPI, 2017-07)
The goal of achieving food safety and quality has become increasingly important in relevant areas. The achievement of this objective includes a significant effort in different areas related to the production of raw materials, ...

New trends in the development of electrochemical biosensors for the quantification of microRNAs
(Elsevier Science, 2020-09)
MicroRNAs (miRNAs) are non-coding regulatory RNAs that play an important role in RNA silencing and post-transcriptional gene expression regulation. Since their dysregulation has been associated with Alzheimer disease, ...
Amperometric response of hydrogen peroxide at carbon nanotubes paste electrodes modified with an electrogenerated poly(Fe(III)-5-amino-phenantroline): Analytical applications for glucose biosensing
(Wiley VCH Verlag, 2010-01-23)
This work reports the catalytic activity of a polymer electrogenerated from Fe(III)-5-amino-1,10-phenantroline solution at a carbon nanotubes paste electrode (CNTPE) towards the oxidation and mainly the reduction of hydrogen ...
