  • Publication number: 20230249974
    Abstract: Atomically thin layers including pores, their method of manufacture, and their use are disclosed. In some embodiments, pores may be formed in an atomically thin layer by growing the atomically thin layer on exposed portions of a substrate that includes islands comprising a material that is different than the material of the substrate. In some embodiments, pores and/or defects may be formed in an atomically thin layer by employing growth conditions that promote the formation of defects and/or pores. In certain embodiments, pores and/or defects may be etched to enlarge their size.

  • Patent number: 11717791
    Abstract: Two-dimensional material based filters, their method of manufacture, and their use are disclosed. In one embodiment, a membrane may include an active layer including a plurality of defects and a deposited material associated with the plurality of defects may reduce flow therethrough. Additionally, a majority of the active layer may be free from the material. In another embodiment, a membrane may include a porous substrate and an atomic layer deposited material disposed on a surface of the porous substrate. The atomic layer deposited material may be less hydrophilic than the porous substrate and an atomically thin active layer may be disposed on the atomic layer deposited material.

  • Patent number: 10065154
    Abstract: Devices and methods integrate nanopore and microfluidic technologies for recording molecular characteristics of individual molecules such as, for example, biomolecules. Devices comprise a first substrate comprising a microchannel, a second substrate comprising a microchannel, the second substrate positioned below the first substrate, and a membrane having a thickness of about 0.3 nm to about 1 nm and comprising at least one nanopore, the membrane positioned between the first substrate and the second substrate, wherein a single nanopore of the membrane is constructed and arranged for electrical and fluid communication between the microchannel of the first substrate and the microchannel of the second substrate. To mitigate the effect of errors that occur during de novo DNA synthesis, longer DNA molecules are typically synthesized from shorter oligonucleotides by polymerase construction and amplification (PCA), or by other methods.

  • Patent number: 8652332
    Abstract: Method and devices for filtering liquid are provided that rely on pressure difference to filter liquid. In one embodiment, a device for filtering liquid includes a feed chamber, a permeate chamber, and a porous membrane that is at least partially hydrophobic and has one or more pores configured to be permeable to vapor. A pressure of a liquid substance in the feed chamber is increased such that vapor of the liquid substance is transported from the feed chamber to the permeate chamber. The resistance of flow in a hydrophilic layer of the membrane can be controlled to make the membrane defect-tolerant. In another embodiment, a second porous membrane is further included and the second porous membrane is spaced apart from the first porous membrane. Various methods for filtering liquid are also provided.

  • Publication number: 20130331792
    Abstract: The present disclosure provides devices and uses thereof. A devices disclosed herein comprises one or more tips, wherein the one or more tips are designed and constructed to initiate penetration by the device; and one or more protrusions in a region adjacent to each tip. In some embodiments, one or more protrusions can be constructed and arranged so that the required penetration force is reduced as compared with that observed for an otherwise identical device lacking the one or more protrusions. Additionally or alternatively, one or more protrusions can be constructed and arranged such that the required pull-out force is increased as compared with that observed for an otherwise identical device lacking the one or more protrusions.
