We perform the characterization of these spin defects and utilize their properties to do omnidirectional magnetic field sensing. We transfer these BNNTs with spin defects onto an AFM cantilever and perform scanning probe magnetometry of a 2D Nickel pattern on a gold waveguide. </p> Quantum optics and quantum optomechanics Quantum technologies quantum sensing devices Quantum optics and quantum optomechanics spin qubit devices 1D materials magnetometry methods
2	Field-effect transistor based biosensing of glucose using carbon nanotubes and monolayer MoS2 Ullberg, Nathan January 2019 (has links) As part of the EU SmartVista project to develop a multi-modal wearable sensor for health diagnostics, field-effect transistor (FET) based biosensors were explored, with glucose as the analyte, and carbon nanotubes (CNTs) or monolayer MoS2 as the semiconducting sensing layer. Numerous arrays of CNT-FETs and MoS2-FETs were fabricated by photolithographic methods and packaged as integrated circuits. Functionalization of the sensing layer using linkers and enzymes was performed, and the samples were characterized by atomic force microscopy, scanning electron microscopy, optical microscopy, and electrical measurements. ON/OFF ratios of 102 p-type and < 102 n-type were acheived, respectively, and the work helped survey the viability of realizing such sensors in a wearable device. / EU Horizon 2020 - SmartVista (825114) field-effect transistor biosensor glucose carbon nanotube MoS2 1D materials 2D materials nanotechnology FET Condensed Matter Physics Den kondenserade materiens fysik Nano Technology Nanoteknik
