Electrochemical detection of plant virus using gold nanoparticle-modified electrodes

Mohga Khater, Alfredo de la Escosura-Muñiz, Daniel Quesada-González, Arben Merkoçi. Analytica Chimica Acta, 2019, Vol 1046, pp 123-131,
Tristeza is one of the destructive diseases of citrus causing by citrus tristeza virus (CTV). Historically, CTV has been associated with serious outbreaks of quick decline of citrus, therefore CTV monitoring is important aspect for avoiding such re-emerging epidemics, which would threat citrus production through the world. In...

Uranium (VI) detection in groundwater using a gold nanoparticle/paper-based lateral flow device

Daniel Quesada-González, Grace A. Jairo, Robert C. Blake II, Diane A. Blake, A. Merkoçi. Scientific Reports, 2018, Vol 8, Article number: 16157
The contamination in groundwater due to the presence of uranium is nowadays a subject of concern due to the severe health problems associated with renal failure, genotoxicity and cancer. The standard methods to detect uranium require time-consuming processes and expensive non-portable equipment, so these measurements are rarely performed...

Nanomaterial-based devices for point-of-care diagnostic applications

Daniel Quesada-González, Arben Merkoçi. Chemical Society Reviews, 2018, Vol 47, pp 4697-4709
In this review, we have discussed the capabilities of nanomaterials for point-of-care (PoC) diagnostics and explained how these materials can help to strengthen, miniaturize and improve the quality of diagnostic devices. Since the optical, electrochemical and other physical properties of nanomaterials are dictated by their composition,...

Mobile phone–based biosensing: an emerging “diagnostic and communication” technology

Daniel Quesada-González, Arben Merkoçi. Biosensors and Bioelectronics, 2017, Vol 92, pp 549-562
In this review we discuss recent developments on the use of mobile phones and similar devices for biosensing applications in which diagnostics and communications are coupled. Owing to the capabilities of mobile phones (their cameras, connectivity, portability, etc.) and to advances in biosensing, the coupling of these two technologies...

An iridium oxide nanoparticle and polythionine thin film based platform for sensitive Leishmania DNA detection

Carmen C. Mayorga-Martinez, Alejandro Chamorro-García,   Lorena Serrano,  Lourdes Rivas,  Daniel Quesada-Gonzalez,   Laura Altet,   Olga Francino,   Armand Sánchez and   Arben Merkoçi   . J. Mater. Chem. B, 2015,3, 5166-5171
An impedimetric label-free genosensor for high sensitive DNA detection is developed. This system is based on a screen-printed carbon electrode modified with the thionine layer and iridium oxide nanoparticles (IrO2 NP). An aminated oligonucleotide probe is immobilized on the IrO2 NP/polythionine modified electrode and ethanolamine...

Nanoparticle-based lateral flow biosensors

Daniel Quesada-González, Arben Merkoçi. Biosensors and Bioelectronics. Volume 73, 15 November 2015, Pages 47–63
Lateral flow biosensors (LFBs) are paper-based devices which permit the performance of low-cost and fast diagnostics with good robustness, specificity, sensitivity and low limits of detection. The use of nanoparticles (NPs) as labels play an important role on the design and fabrication of a lateral flow strip (LFS). The choice of...

Label-free Impedimetric Aptasensor for Ochratoxin-A Detection Using Iridium Oxide Nanoparticles

Lourdes Rivas , Carmen C. Mayorga-Martínez , Daniel Quesada-González , Alejandro Zamora , Alfredo de la Escosura-Muñiz , and Arben Merkoçi. Anal. Chem., 2015, 87 (10), pp 5167–5172
In this article, a novel aptasensor for ochratoxin A (OTA) detection based on screen-printed carbon electrode (SPCE) modified with polythionine (PTH) and iridium oxide nanoparticles (IrO2 NPs) is presented. The electrotransducer surface is modified with an electropolymerized film of PTH followed by the assembly of IrO2 NPs that aminated...
