Electromechanical Detection of Pathogens with Self-Assembled Nucleic Acid Biosensors

Bahnemann J., Chikneyan Z., Hoffmann M.R., Kasmaee L.M., Urmann K., California Institute of Technology, US

Infectious diseases, primarily caused by enteric pathogens, remain a major cause of death, especially in remote locations of the developing world. Routine monitoring of pathogen contaminations is therefore crucial. We seek to apply quartz crystal [...]

High-sensitive, direct and label-free detection technique of nanotoxic material using QCM

Jang K., Na S., Park C., Park J., You J., Korea university, KR

For the several decades, various nanomaterials are broadly used in industrial fields, research areas and commercialized products. Among many nanomaterials, silver ion, carbon nanotube, ZnO, and mercury ion etc are of the widely used nanomaterial [...]

Characterisation of Graphene in Liquid and Gaseous Environment with Quartz Crystal Microbalance for Applications in Real-Life Energy Storage Devices

Kolosov O., Mazzocco R., Robinson B., Lancaster University, UK

Graphene is a flat monolayer of carbon atoms whose extraordinary properties are to revolutionize the performance of many technological applications. Unfortunately there is very little understanding of how the properties of graphene change in its [...]

Thermodynamic Characterization of Nanoscale Materials

Smith A.L., Masscal Corporation, US

“The largest barrier to rational design and controlled synthesis of nanomaterials with predefined properties is the lack of fundamental understanding of thermodynamic and kinetic processes at the nanoscale. …Bulk material properties are not size-dependent, but [...]

The Use of Quartz Crystal Microbalance in Cell Differentiation Detection

Ke W-W, Lieu C-H, Shih C-J, Industrial Technology Research Institute/Electronics Research & Service Organization, TW

We try to investigate whether the hematopoietic cell differentiation can be detected by Quartz Crystal Microbalance. Because certain hematopoietic transcription factors play a critical role in cell differentiation and lineage determination, they can be alternate [...]

Surface Characterization of a Direct, Label-Free Piezoelectric Immunosensor Platform

Barrero-Moreno J., Ceccone G., Gilliland D., Lejeune M., Manso M., Papadopoulou-Bouraoui A., Rossi F., Valsesia A., European Commission - JRC, IT

During this study the QCM (Quartz Crystal Microbalance) crystal surface was functionalized in order to provide active amino groups, and serve as an active platform for antibody immobilization and the development of direct, label-free immunosensors. [...]

A Novel Polymer Nanofiber Interface for Chemical and Biochemical Sensor Applications

Han B., Ko F.K., Kwoun S.J., Lee R.M., Drexel University, US

Polymer thin films are used extensively as a chemically sensing medium in variety types of acoustic sensors. It is well known that the sensitivity of a sensing film is proportional to the surface area of [...]
