Broadband 120 MHz Impedance Quartz Crystal Microbalance (QCM) with Calibrated Resistance and Quantitative Dissipation for Biosensing Measurements at Higher Harmonic Frequencies

We developed an impedance quartz crystal microbalance (QCM) approach with the ability to simultaneously record mass changes and calibrated energy dissipation with high sensitivity using an impedance analyzer. This impedance QCM measures frequency shifts and resistance changes of sensing quartz crystals very stable, accurately, and calibrated, thus yielding quantitative information on mass changes and dissipation. Resistance changes below 0.3 Ω were measured with corresponding dissipation values of 0.01 µU (micro dissipation units). The broadband impedance capabilities allow measurements between 20 Hz and 120 MHz including higher harmonic modes of up to 11th order for a 10 MHz fundamental resonance frequency quartz crystal. We demonstrate the adsorbed mass, calibrated resistance, and quantitative dissipation measurements on two biological systems including the high affinity based avidin-biotin interaction and nano-assemblies of polyelectrolyte layers. The binding affinity of a protein-antibody interaction was determined. The impedance QCM is a versatile and simple method for accurate and calibrated resistance and dissipation measurements with broadband measurement capabilities for higher harmonics measurements

The neural correlates of health risk perception in individuals with low and high numeracy

The ability to use numerical information in different contexts is a major goal of mathematics education. In health risk communication, outcomes of a medical condition are frequently expressed in probabilities. Difficulties to accurately represent probability information can result in unfavourable medical decisions. To support individuals with low-numeracy skills, pictographs such as graphs or icon arrays have been proposed to increase risk communication. The neurocognitive mechanism underlying the processing of health risk perception in individuals with low- and high-numeracy remain to be explored. To investigate the neural correlates of health risk perception, the brain responses of individuals with low- and high-numeracy were measured using functional magnetic resonance imaging. In the health risk perception condition, participants were instructed to indicate how concerned they would be of having cancer, given an icon array in which the probability of developing cancer was displayed. In the number line condition the same icon arrays were presented and participants were instructed to indicate the absolute number of displayed black icons. Results of the study showed that the low-numeracy group was more accurate in the health risk condition compared to the high-numeracy group, which overestimated health risks. A comparison of brain activation between the groups demonstrated that the high-numeracy group expressed larger brain engagement during the health risk condition in regions that are commonly associated with conflict monitoring, decision-making and emotional processing. These results provide initial evidence that individuals with high-numeracy engage regions of the brain to a different extent compared to individuals with low-numeracy.ISSN:1615-679XISSN:1863-969
