Custom Sensors Technology Note – Custom Coating QCM

/in , /by

September 14th 2021: AWSensors is pleased to invite you to take a look to its new Technology Note entitled “Custom Sensors”.

Custom AWSensors Sensors

Summary of the Note

This Technology Note describes how to use of custom-coated QCMD sensors with AWSensors instruments. AWS Suite software has a Custom Sensor feature that allows the user to add custom-coated sensors to their sensor list and configure their electrical parameters so that the software can perform the search and characterization of the resonance parameters of the sensors during automatic setup.

Introduction

AWSensors instruments can characterize a wide range of sensors: classical low-frequency (5 MHz to 10 MHz) QCMD, high-frequency (HFF) QCMD, and Love- Surface Acoustic Wave (Love-SAW). Furthermore, an important aspect of the AWSensors QCMD technology is the flexibility the customer has in terms of surface coatings of the QCMD sensors. The AWS Suite software includes the default configurations for many “standard” sensors supplied by us. Moreover, it allows the user to work with custom sensors, where the coating has affected the resonance properties. Some third-party sensors, compatible with the AWSensors measurement cells, may also benefit from this feature.

Up to five custom sensors can be defined by the user by introducing measured resonance properties. This Technical Note provides a description of this feature and a step-by-step guide for its use.

Ayuda InnovaTEIC 2020 IVACE concedida

/in , /by

06/08/2021. Advanced Wave Sensors S.L. (AWSensors) ha sido seleccionada como beneficiaria de una ayuda concedida por el Instituto Valenciano de Competitividad Empresarial (IVACE) para llevar a cabo el proyecto “Diseño, desarrollo e industrialización de un instrumento QCM-D de alta resolución multicanal” en el marco del programa InnovaTEIC 2020. Este programa ha sido financiado parcialmente por el Fondo Europeo de Desarrollo Regional (FEDER) dentro del Programa Operativo FEDER de la Comunitat Valenciana 2014-2020 cuyo objetivo es mejorar la competitividad de las PYMES valencianas.

La presente actuación ha servido para desarrollar un nuevo instrumento científico, denominado X4, para la caracterización de sensores acústicos basado en una técnica protegida por la patente internacional PCT/ES2010/070409 en explotación actualmente por AWSensors. La plataforma X4 es capaz de caracterizar diferentes tipos de sensores micro/nanogravimétricos: QCM-D, HFF-QCM, SAW-LOVE, Torsional Wave,… que se emplean habitualmente en la detección y/o monitorización de interacciones biomoleculares como: reacciones antígeno-anticuerpo, detección de patógenos como bacterias y virus, adhesión celular, caracterización de la absorción de proteínas e interacciones DNA y RNA con secuencias complementarias. El rango de aplicaciones del citado instrumento es muy amplio y va desde la detección de patógenos en diagnóstico o seguridad alimentaria hasta la caracterización de las propiedades de nuevos nanomateriales.

Las principales innovaciones que presenta este dispositivo son: incremento en la velocidad de caracterización, paralelización de ensayos con la posibilidad caracterizar hasta 4 sensores simultáneamente, reducción de peso y tamaño para un instrumento semi-portable, mejora de la estabilidad térmica, mejora del diseño e inclusión de herramientas de post-procesado en software.

Cobalt EQCM Application Note

/in , /by

July 2nd 2021: AWSensors is pleased to invite you to take a look to its Cobalt EQCM Application Note entitled “Cobalt Deposition and Dissolution“.

Cobalt EQCM Application Note

Summary of the Note

Use of AWS A20 RP in combination with a compatible potentiostat to perform an electrochemical study of deposition and dissolution of metallic layers onto the gold electrode of an AWS HFF-QCM sensor.

Materials and Methods

Materials:

A 100MHz AWS HFF-QCM sensor was used with AWS A20 RP platform in combination with the SP-200 floating mode Potentiostat/Galvanostat from Biologic. The signals associated with the sensor phase monitoring in the AWS A20RP and the current and potential measurement of the SP-200 were monitored. The deposition solution was 10mM K2SO4 + 0.001M KCl + 0.001M H2SO4 + 0.001M (CoSO4)·7H2O solution. A Pt counter electrode was used with a saturated KCl solution Ag/AgCl reference electrode. The working electrode was the grounded electrode of the AWS HFF-QCM sensor.

Cyclic Voltametry:

Determination of the Nernst equilibrium potential and the investigation of the overpotential deposition of Cobalt on the gold electrode of the HFFQCM. The potential was held at –0.4V ten seconds before starting the cyclic voltammetry. A potential scan with a rate of 10mV/s was applied from –0.4 to –1.5V.

Underpotential Deposition:

Controlled deposition of atomic layers of Cobalt on the AWS HFF-QCM sensor.

New QCMD Immunosensor Application Note

/in , /by

May 20th 2021: AWSensors is pleased to invite you to take a look to its new Immunosensor Application Note entitled “QCMD immunosensor for small molecule analytes“.

Summary of the Note

A QCMD-based immunoassay for label-free analysis of small molecule concentration in industrial samples was developed using an AWS QCMD system with surface-modified 5 MHz fundamental frequency QCMD sensors. Accuracy and precision of the immunoassay is evaluated with respect to the industry-standard HPLC reference.

QCMD Immunosensor

Introduction

Accurate, rapid, and cost-effective quantification of small molecule analytes is a pressing problem in various industrial (food, agriculture, environmental protection) and health-related fields. Existing approaches include enzyme-linked immunosorbent assays (ELISAs) and various types of chromatography (e.g., High Performance Liquid Chromatography, HPLC). These approaches require trained personal and centralized laboratories, and their deployment in the field is difficult or impossible.

Quartz Crystal Microbalance with Dissipation, or QCMD, is emerging as a promising technology for the development of fast, portable, automated, and cost-effective immunosensors. Here, we demonstrate a competitive small molecule immunoassay based on the AWSensors QCMD technology.
