“…15 Flow cytometry has remained the preferred method for cell sorting by many biologists 16 because the technique is well established and has both high sensitivity and high throughput. 17 Recently, fluorescence based sorting of cells and particles has also been implemented in 18 microfluidic devices. 19 The microfluidic separation techniques are broadly classified as being either passive or 20 active, depending on the operating principles ( Acoustophoresis is the separation of particles using high intensity sound waves.…”

“…Moreover, the system is easy to handle and very biocompatible. 16 Despite the many advantages of streptavidin, a major drawback is the instability at low or 17 high pH values, and high temperature. For some detection methods the rather thick protein 18 layer between electrode and probe can substantially decrease the sensitivity of the sensor.…”

“…Such composite materials are not uncommon, having been a focus or research for use as conductive tracks and electrodes, chemical sensors and thin film transistors, and often comprise nanoscale conductive filler particles dispersed in a flowing polymer. [16][17][18][19][20] The progression to nanoscaled filler particles has enabled the use of ink-jet printing for many of these composite materials; larger particles tend to clog the printer nozzles. This work presents a description of the functional behaviour and physical structure of a new type of screen-printed composite ink with electrical properties that are highly sensitive to applied force.…”

Abstract. Printable electronics is an innovative area of technology with great commercial potential. Here, a screen-printed functional ink, comprising a combination of semi-conductive acicular particles, electrically insulating nanoparticles and a base polymer ink, is described that exhibits pronounced pressure sensitive electrical properties for applications in sensing and touch sensitive surfaces. The combination of these components in the as-printed ink affect a complex structure and a large and reproducible touch pressure sensitive resistance range. In contrast to some composite systems, the resistance changes occur down to applied pressures of 13 Pa. Current-Voltage measurements at fixed pressures show monotonic non-linear behaviour, which becomes more ohmic at higher pressures and in all cases shows some hysteresis. The physical basis for conduction, particularly in the low pressure regime, can be described in terms of field assisted quantum mechanical tunnelling.2

Abstract-Here, a novel functional ink is described that is composed of multiple nanoscale components and exhibits pronounced touch pressure sensitive electrical properties ideal for applications in switching, sensing and touch sensitive surfaces. The ink can be screen-printed and the as-printed ink displays a large and reproducible touch pressure sensitive electrical resistance and, in contrast to some other composite materials, the resistance changes occur down to the smallest applied pressures. Detailed scanning electron microscopy shows the complex nanoscale structure of the composite that is critical for the electrical behavior. Current-voltage measurements, under static compressive loading, show monotonic nonlinear behavior at low compression and ohmic behavior at higher loadings.
