Avidin-gated mesoporous silica nanoparticles for signal amplification in electrochemical biosensor

Jimenez-Falcao, Sandra; Parra-Nieto, Jorge; Pérez-Cuadrado, Hugo; Martínez-Máñez, Ramón; Martínez-Ruiz, Paloma; Villalonga, Reynaldo (Elsevier, 2019-11)

[EN] We report herein a novel sensing strategy for electrochemical biosensors, by using mesoporous silica nanoparticles loaded with the redox probe methylene blue and capped with an avidin/imminobiotin stimulus-responsive ...
Electrochemical bio- and chemosensors for cancer biomarkers: Natural (with antibodies) versus biomimicking artificial (with aptamers and molecularly imprinted polymers) recognition

Moussa, Fatah Ben; Kutner, Wlodzimierz; Beduk, Tutku; Sena-Torralba, Amadeo; Mostafavi, Ebrahim (Elsevier, 2024-01-15)

[EN] Electrochemical (EC) bio- and chemosensors are highly promising for on-chip and point-of-care testing (POST) devices. They can make a breakthrough in early cancer diagnosis. Most current EC sensors for cancer biomarkers' ...
Fluorogenic Sensing of Carcinogenic Bisphenol A using Aptamer-Capped Mesoporous Silica Nanoparticles

Ribes, Àngela; Aznar, Elena; Bernardos Bau, Andrea; Marcos Martínez, María Dolores; Amorós, Pedro; Martínez-Máñez, Ramón; Sancenón Galarza, Félix (John Wiley & Sons, 2017)

[EN] Mesoporous silica nanoparticles loaded with rhodamine B and capped with a bisphenol A aptamer were used for the selective and sensitive detection of this lethal chemical. The pores of the nanoparticles are selectively ...
