    Abstract: Techniques for differentiating isobaric species are described. An isobaric species may be substituted with a tagging species identified using mass spectrometry. The isobaric species may be a subunit of a first polymer having a defined sequence, e.g., the isobaric species may be an amino acid in a protein or a peptide sequence. A tagging species may be substituted for the isobaric species in a second polymer having an otherwise identical sequence as the first polymer. The second polymer may have the same number of sequences as the first polymer, and substantially the same sequence of subunits, with a few exceptions such as the tagging species for the isobaric species. The first polymer and the second polymer may be prepared in the same reaction vessel. A polymer/protein of defined subunit sequence containing an isobaric species or a tagging species may be analyzed by mass spectrometry to determine the sequence.

    Abstract: Provided herein are methods and systems for detecting and/or sorting targets in a sample based on the combined use of polynucleotide-encoded protein and substrate polynucleotides. The polynucleotide-encoded protein is comprised of a protein that specifically binds to a predetermined target and of an encoding polynucleotide that specifically binds to a substrate polynucleotide, wherein the substrate polynucleotide is attached to a substrate.

    Abstract: Described herein are inventive compositions and methods relating to sampling of biopolymers and, in particular, to fractional sampling of biopolymers. In one aspect, embodiments are generally related to unique biopolymer species where a fraction of each biopolymer species contains a cleavable linker. The biopolymer species may, in some embodiments, be attached to a surface. For example, the biopolymer species may be attached to beads. In some embodiments, a portion of a unique biopolymer species may be sampled by cleaving the cleavable linker. In some cases, the sample may be analyzed to determine the sequence of the biopolymer.

    Abstract: Fabrication of metallic or non-metallic wires with nanometer widths and nanometer separation distances without the use of lithography. Wires are created in a two-step process involving forming the wires at the desired dimensions and transferring them to a planar substrate. The dimensions and separation of the wires are determined by the thicknesses of alternating layers of different materials that are in the form of a superlattice. Wires are created by evaporating the desired material onto the superlattice that has been selectively etched to provide height contrast between layers. The wires thus formed upon one set of superlattice layers are then transferred to a substrate.
