Deciphering the neuronal code—the rules by which neuronal circuits store and process
information—is a major scientific challenge 1 , 2 . Currently, these efforts are impeded by a lack …

Precisely timed activation of genetically targeted cells is a powerful tool for the study of
neural circuits and control of cell-based therapies. Magnetic control of cell activity, or ‘…

Fabricating inorganic materials with designed three-dimensional nanostructures is an
exciting yet challenging area of research and industrial application. Here, we develop an …

A generalized platform for introducing a diverse range of biomolecules into living cells in
high-throughput could transform how complex cellular processes are probed and analyzed. …

We demonstrate a chip-scale photonic system for the room-temperature detection of gas
composition and pressure using a slotted silicon microring resonator. We measure shifts in the …

We demonstrate low loss silicon waveguides fabricated without any silicon etching. We define
the waveguides by selective oxidation which produces ultra-smooth sidewalls with width …

Implantable bioelectronic devices for the simulation of peripheral nerves could be used to
treat disorders that are resistant to traditional pharmacological therapies. However, for many …

We theoretically demonstrate a mechanism for reduction of mode volume in high index contrast
optical microcavities to below a cubic half wavelength. We show that by using dielectric …

Beyond the more common chemical delivery strategies, several physical techniques are
used to open the lipid bilayers of cellular membranes 1 . These include using electric 2 and …

From first principles we develop figures of merit to determine the gain experienced by the
guided mode and the lasing threshold for devices based on high-index-contrast waveguides. …
