A DNA-Based Magnetic Sensor
Northern wheatearssmall migratory songbirds that weigh about the same as an AA batteryfly 30,000 km every year from Alaska via Asia to Kenya and back again. Their ability to do so depends crucially on having an internal magnetic compass with which to sense the Earth’s magnetic field. It appears that all avian migrants have such a light-dependent compass. Although it is clear that the primary ...
متن کاملMagnetic and gold-coated magnetic nanoparticles as a DNA sensor.
In this study, we report the chemical synthesis and functionalization of magnetic and gold-coated magnetic nanoparticles and the immobilization of single-stranded biotinylated oligonucleotides onto these particles. Selected sequences specific to the BRCA1 gene were used as a test platform. The binding of oligonucleotides to these particles was achieved through a streptavidin-biotin bridge via a...
متن کاملA magnetic cell-based sensor.
Cell-based sensing represents a new paradigm for performing direct and accurate detection of cell- or tissue-specific responses by incorporating living cells or tissues as an integral part of a sensor. Here we report a new magnetic cell-based sensing platform by combining magnetic sensors implemented in the complementary metal-oxide-semiconductor (CMOS) integrated microelectronics process with ...
متن کاملCMOS - based DNA Sensor Arrays
The invention of the transistor some 50 years ago, the subsequent realization of integrated circuits and today’s availability of complete systems-on-a-chip have had an essential impact on today’s way of life. The next revolution of similar impact may arise from developments in the area of biotechnology and life sciences. In this field, tools are required which can – in some cases only – be prov...
متن کاملSelf-powered magnetic sensor based on a triboelectric nanogenerator.
Magnetic sensors are usually based on the Hall effect or a magnetoresistive sensing mechanism. Here we demonstrate that a nanogenerator can serve as a sensor for detecting the variation of the time-dependent magnetic field. The output voltage of the sensor was found to exponentially increase with increasing magnetic field. The detection sensitivities for the change and the changing rate of magn...
