  • Detection of the melanoma biomarker TROY using silicon nanowire field-effect transistors 

    Maedler, Carsten; Kim, Daniel; Spanjaard, Remco A.; Hong, Mi; Erramilli, Shyamsunder; Mohanty, Pritiraj
    Antibody-functionalized silicon nanowire field-effect transistors have been shown to exhibit excellent analyte detection sensitivity enabling sensing of analyte concentrations at levels not readily accessible by other ...
  • Wireless actuation of micromechanical resonators 

    Mateen, Farrukh; Maedler, Carsten; Erramilli, Shyamsunder; Mohanty, Pritiraj (NATURE PUBLISHING GROUP, 2016-08-15)
    The wireless transfer of power is of fundamental and technical interest, with applications ranging from the remote operation of consumer electronics and implanted biomedical devices and sensors to the actuation of devices ...
  • Wireless actuation of bulk acoustic modes in micromechanical resonators 

    Mateen, Farrukh; Brown, Benjamin; Erramilli, Shyamsunder; Mohanty, Pritiraj (AMER INST PHYSICS, 2016-08-15)
    We report wireless actuation of a Lamb wave micromechanical resonator from a distance of over 1 m with an efficiency of over 15%. Wireless actuation of conventional micromechanical resonators can have broad impact in a ...
  • Quantum friction of micromechanical resonators at low temperatures 

    Ahn, Kang-Hun; Mohanty, Pritiraj (2003-02-28)
    Dissipation of micro- and nanoscale mechanical structures is dominated by quantum-mechanical tunneling of two-level defects intrinsically present in the system. We find that at high frequencies-usually, for smaller, ...
  • Nanomechanical detection of the spin Hall effect 

    Boales, J.A.; Boone, C.T.; Mohanty, P. (AMER PHYSICAL SOC, 2016-04-27)
    The spin Hall effect creates a spin current in response to a charge current in a material that has strong spin-orbit coupling. The size of the spin Hall effect in many materials is disputed, requiring independent measurements ...
  • Intrinsic decoherence in mesoscopic systems 

    Mohanty, P.; Jariwala, E.M.Q.; Webb, R.A. (AMERICAN PHYSICAL SOC, 1997-04-28)
    We present measurements of the phase coherence time τ φ in six quasi-1D Au wires and clearly show that τ φ is temperature independent at low temperatures. We suggest that zero-point fluctuations of the phase ...
  • Field Effect Transistor Nanosensor for Breast Cancer Diagnostics 

    Mohanty, Pritiraj; Chen, Yu; Wang, Xihua; Hong, Mi K.; Rosenberg, Carol L.; Weaver, David T.; Erramilli, Shyamsunder (2012)
    Silicon nanochannel field effect transistor (FET) biosensors are one of the most promising technologies in the development of highly sensitive and label-free analyte detection for cancer diagnostics. With their exceptional ...
  • Perspective: Melanoma diagnosis and monitoring: Sunrise for melanoma therapy but early detection remains in the shade 

    Spanjaard, Remco; Weaver, David; Erramilli, Shyamsunder; Mohanty, Pritiraj
    Melanoma is one of the most dangerous forms of cancer. The five-year survival rate is 98% if it is detected early. However, this rate plummets to 63% for regional disease and 17% when tumors have metastasized, that is, ...
  • Optical wireless information transfer with nonlinear micromechanical resonators 

    Boales, Joseph A.; Mateen, Farrukh; Mohanty, Pritiraj (NATURE PUBLISHING GROUP, 2017-08-28)
    Wireless transfer of information is the basis of modern communication. It includes cellular, WiFi, Bluetooth, and GPS systems, all of which use electromagnetic radio waves with frequencies ranging from typically 100 MHz ...
  • Micromechanical resonator driven by radiation pressure force 

    Boales, Joseph A.; Mateen, Farrukh; Mohanty, Pritiraj (2017-11-22)
    Radiation pressure exerted by light on any surface is the pressure generated by the momentum of impinging photons. The associated force - fundamentally, a quantum mechanical aspect of light - is usually too small to be ...
