Frequency stabilization in nonlinear micromechanical oscillators
(Springer, 2012-01)
Mechanical oscillators are present in almost every electronic device. They mainly consist of a resonating element providing an oscillating output with a specific frequency. Their ability to maintain a determined frequency ...
Diseño y evaluación de un micro viscosímetro de bajo costo utilizando un resonador de cristal de cuarzo y Arduino
(Universidad de los Llanos, 2017-07-16)
El objetivo principal de este artículo es proponer el diseño de un micro viscosímetro de bajo coste utilizando un resonador de cristal de cuarzo (QCR) y una tarjeta Arduino DUE. En el artículo se explican los pasos del ...
A new immunoassay of hybrid nanomater conjugated to aptamers for the detection of dengue virus
(2019-05-15)
A new immunosensor using hybrid nanomaterials for the detection of dengue virus was demonstrated in this work. This immunosensor composed of nanoparticles of γ-Fe2O3(SAMN) modified with MPA- SAMN@MPA was characterized by ...
Adsorption of cobalt ferrite nanoparticles within layer-by-layer films: a kinetic study carried out using quartz crystal microbalance
(Royal Society of Chemistry - RSCCambridge, 2011)
The paper reports on the successful use of the quartz crystal microbalance technique to assess accurate kinetics and equilibrium parameters regarding the investigation of in situ adsorption of nanosized cobalt ferrite ...
Effect of Charge Asymmetry on Adsorption and Phase Separation of Polyampholytes on Silica and Cellulose Surfaces
(AMER CHEMICAL SOC, 2010)
The relation between the properties of polyampholytes in aqueous solution and their adsorption behaviors on silica and cellulose surfaces was investigated. Four polyampholytes carrying different charge densities but with ...
Piezoelectric biosensors for real-time monitoring of hybridization and detection of hepatitis C virus
(Elsevier B.V., 2004-05-01)
The piezoelectric quartz crystal resonators modified with oligonucleotide probes were used for detection of hepatitis C virus (HCV) in serum. The gold electrodes on either rough or smooth surface crystals were modified ...
