Abstract: This disclosure describes a structured polynucleotide, devices that include the structured polynucleotide, and methods involving the structured polynucleotide and/or devices. Generally, the structured polynucleotide includes five domains. A first domain acts as a toehold for an input DNA logic gate to initiate binding to an SCS biomolecule. A second domain acts as a substrate recognition sequence for an upstream DNA logic gate. A third domain acts as a toehold for a output DNA logic gate to initiate binding of the SCS biomolecule to the gate. A fourth domain acts as an effector sequence to alter the state of the output logic gate. A fifth domain acts as a cage sequence to lock the effector sequence in an inactive state until an input gate binds to the structured polynucleotide.

Abstract: Methods and apparatus for long read, label-free, optical nanopore long chain molecule sequencing. In general, the present disclosure describes a novel sequencing technology based on the integration of nanochannels to deliver single long-chain molecules with widely spaced (>wavelength), ˜1-nm aperture “tortuous” nanopores that slow translocation sufficiently to provide massively parallel, single base resolution using optical techniques. A novel, directed self-assembly nanofabrication scheme using simple colloidal nanoparticles is used to form the nanopore arrays atop nanochannels that unfold the long chain molecules. At the surface of the nanoparticle array, strongly localized electromagnetic fields in engineered plasmonic/polaritonic structures allow for single base resolution using optical techniques.

Abstract: A solar cell for collecting solar radiation can include a barrier layer such as a dielectric barrier layer and a heterostructure including a first light absorbing layer and at least a second light absorbing layer. A method for forming the solar cell can include forming a sacrificial layer on a support substrate and forming the barrier layer on the sacrificial layer. The barrier layer is formed to have a strain gradient through its thickness. The heterostructure is attached to the barrier layer and the sacrificial layer is removed, thereby separating the barrier layer and the heterostructure from the support substrate. During the removal of the sacrificial layer, the strain gradient causes the barrier layer and heterostructure, to roll, curl, or spiral, thereby resulting in a radially stacked heterostructure that provides a light concentrating optical cavity having multiple light absorbing layers with different band gaps.
