The difference the “D” makes in QCMD

AWSensors presents a new Technology Note on the importance of dissipation measuring when working with QCMD: “The difference the “D” makes in QCMD”.

Dissipation

What is dissipation, and why it is useful?

Quartz Crystal Microbalance with Dissipation, or QCMD, is having a tremendous impact on research in the soft and biological interfaces fields because of its versatility and the wealth of information it provides. In this Technology Note, we discuss the origins of dissipation in the different systems studied by QCMD, from complex fluids and polymer films to biomolecular and particle assemblies, and the information dissipation can provide, from characterizing viscoelasticity to studying molecular conformation.

In this Technical Note we discuss the origins of dissipation, how it can be used to verify the applicability of the Sauerbrey relationship and their interaction with the viscoelasticity and in the biological sensing.

AWSensors cooperation with UPVfab

AWSensors, one of the first spin-off companies to emerge from the Polytechnic University of Valencia (UPV), sees a space for cooperation with UPVfab. Located at the Polytechnic City of Innovation (UPV’s Science Park), UPVfab is a breakthrough project, counting with a ~500 m2 clean room space and equipped with high-tech instruments, with applications in the areas of research in Photonics, Electronics and Chemistry.

In this initiative participate five research institutes located at the UPV: the Institute of Telecommunications and Multimedia Applications (iTEAM), the Instituto de Tecnología Quimica (ITQ-CSIC), the Instituto de Instrumentación para Imagen Molecular (I3M, UPV-CSIC), el Center for Research and Innovation in Bioengineering, and the Interuniversity Research Institute for Molecular Recognition and Technological Development (IDM) (IDM, UPV-UV).

However, this new project not only seeks to support academic research, but to strengthen its cooperation with industry partners as well. Prof. Antonio Arnau, full professor at UPV’s Department of Electronic Engineering and founder of AWSensors, acknowledges the importance of having these kind of installations that would make possible to validate new developments based on AWSensors’ proprietary array Quartz Crystal Microbalance with Dissipation (QCMD) biosensor technology. The company is already testing this technology in Healthcare applications, as an instrument for precision medicine through fast and simple diagnosis of cancer mutations for a personalized treatment and monitoring of its evolution.

AWSensors is always interested in productive public and private partnerships that help us further the developments in QCMD devices, sensors, and applications of interest.

QCMD Immunosensor

New QCMD Immunosensor Application Note

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.

Antibodies

Antibody Detection with Quartz Crystal Microbalance

May 10th 2021: AWSensors offers acoustic sensors for antibody detection. Acoustic biosensor-based immunosensing with  High-Fundamental Frequency Quartz Crystal Microbalance (HFF-QCM) and Love-SAW sensors offers several advantages over Enzyme Linked Immuno Assay (ELISA) or Surface Plasmon Resonance (SPR).

Acoustic sensors antibody detection advantages over ELISA

  • Sensitivity approximately as a standard ELISA or better.
  • Acoustic sensors offer label-free detection of the antibody-antigen binding.
  • Full automation.
  • Pre-calibrated (the user does not need to run the standards. More samples can be run. Reduced cost per sample).
  • Speed.
  • Quantitative real-time /in-situ monitoring.
  • Turn-key solution (no need to specialized detection equipment, reader, or spectrophotometer).
  • Reduced complexity, relaxed requirements for trained personnel.
  • Small volumes (~ 10 of ul per sample).
  • Parallelization and multiple analyte detection through sensor arrays.
  • Sensor re-usablity, leading to reduced assay cost.

Acoustic sensors antibody detection advantages over SPR

  • Better sensitivity.
  • QCM also sees solvent.
  • Provides conformational information of the surface film.
  • Miniaturization and integration into portable systems.
  • Easier to develop parallel and multiple analyte assays through sensor arrays.
  • Affordability.

Therefore, one can develop biosensors based on acoustic immunosensors with highly attractive features in order to rapidly detect pathogens like viruses and bacteria [1], and low molecular weigh compounds.

Application Example

Our Biosensor Application Note  is an application example where we describe a sensitive detection of a low molecular weight pesticide carbaryl using competitive immunoassay with hapen-conjugates immobilized on high-fundamental frequency QCMD sensors, SAMs and monoclonal antibodies (MAb) [2, 3]. As a result, we achieved a very sensitive detection of the carbaryl analyte.

QCMD in Lipid Research

QCMD in Lipid Research Tech Note

October 15th 2020: AWSensors is pleased to invite you to take a look to its Technology Note entitled “QCMD in Lipid Research”.

Summary of the Note

QCMD is a label-free surface-analytical technique based on a quartz resonator excited to oscillate at its resonance frequency on one or more overtones. Resonators can have various coatings: gold (Au), silica (SiO2), titania (TiO2), etc. It works in aqueous media or organic solvents and is therefore widely used for studying solid/liquid interfaces. At each overtone, QCMD measures changes in the resonance frequency and energy dissipation due to the processes occurring at the resonator surface. Examples of such processes include formation of a film or changes in the geometrical or physical properties of the film.

The key feature that makes QCMD useful in lipid research is its ability to distinguish between different geometries and topologies of lipidic assemblies at interfaces, for example, homogenous solid-supported bilayers or monolayers vs. adsorbed liposomes or other structures (such as cubosomes) without relying on fluorescent or deuterated labels but by relying on the combination of the frequency and dissipation.

QCMD in Lipid Research

Introduction

Lipid-related QCMD work can be grouped into several topics, with a total of more than a thousand publications:
• Studies focusing on the interactions between lipids and surfaces.
• Studies focusing on the properties of the lipids, such as their phase behavior, adsorbed liposome deformation, etc.
• Studies examining interactions between lipids and membrane-binding proteins, peptides or viruses. Particularly interesting is that QCMD offers a way to study clustering of membrane-bound proteins.
• Studies focusing on the interactions of lipids with polymers or with nanoparticles.
