TL;DR: The experimental demonstration and the theoretical framework provide a comprehensive description of the performance potential of dielectric-free MoS2-based biosensor technology.

TL;DR: Large-area and highly crystalline CVD-grown multilayer MoSe2 films exhibit a well-defined crystal structure (2H phase) and large grains reaching several hundred micrometers and suggest that high mobility materials will be indispensable for various future applications such as high-resolution displays and human-centric soft electronics.

TL;DR: This work has developed a fast, low cost, non-faradaic impedance sensing method for detection of synthetic DNA molecules in DI water at attomolar levels by beating the diffusion limit through evaporation of a micro-liter droplet of DNA on a nanotextured superhydrophobic electrode array.

TL;DR: The key challenges that must be addressed to make label-free, droplet-based biosensors commercially viable are identified and a number of promising research directions are summarized.

TL;DR: A general numerical/analytical theory of non-faradaic impedance of an evaporating droplet, and validated the model by experiments involving droplets of various analyte concentrations deposited on a surface defined by coplanar electrodes.
