Significance: Time-domain functional near-infrared spectroscopy (TD-fNIRS) has been considered as the gold standard of noninvasive optical brain imaging devices. However, due to the high cost, complexity, and large form factor, it has not been as wid

Single-molecule measurements of biomolecules can provide information about the molecular interactions and kinetics that are hidden in ensemble measurements. However, there is a requirement for techniques with improved sensitivity and time resolution

Technological advances in fluorescent probes, solid-state imagers, and microscopy techniques have enabled biomolecular studies at the single-molecule level. Fluorescent techniques are highly specific but their bandwidth is fundamentally limited by th

Point-functionalized carbon nanotube field-effect transistors can serve as highly sensitive detectors for biomolecules. With a probe molecule covalently bound to a defect in the nanotube sidewall, two-level random telegraph noise (RTN) in the conduct

Traditionally, biomolecular systems have been studied in ensemble. While much can be determined with ensemble measurements, scientific and technological interest is rapidly moving to single-molecule techniques, which rely primarily on fluorescent mar

We present a label-free single-molecule based sensing platform using a carbon nanotube field-effect transistor. By point functionalizing a carbon nanotube through an electrochemical oxidation reaction, the conductance becomes sensitive and chemically

We have demonstrated that carbon-nanotube field-effect transistors act as highly sensitive single-molecule detectors when point functionalized. The hybridization kinetics of two complementary strands of DNA are associated with two-level fluctuations

Graphene devices on standard SiO2 substrates are highly disordered, exhibiting characteristics far inferior to the expected intrinsic properties of graphene[1-12]. While suspending graphene above the substrate yields substantial improvement in device

This paper describes the design of an active, integrated CMOS sensor array for fluorescence applications which enables time-gated, time-resolved fluorescence spectroscopy. The 64-by-64 array is sensitive to photon densities as low as 8.8 times 106 ph

We report on a capacitance study of dual gated bilayer graphene. The measured capacitance allows us to probe the electronic compressibility as a function of carrier density, temperature, and applied perpendicular electrical displacement $\overline{D}
