The present disclosure provides methods and systems for cell processing, including delivery of substances into cells. The methods and systems may comprise the use of a microfluidic device. The microfluidic device may comprise a channel comprising a compressive element. The compressive element may be configured to reduce a volume of the cell and facilitate the formation of one or more transient pores in a cell membrane of the cell. The one or more pores may permit one or more substances such as therapeutic or gene-editing reagents to enter the cell. Also provided are modified cells produced using the disclosed methods and systems.

The present disclosure provides a system comprising a communication interface and computer for assigning a label to the biomolecule fingerprint, wherein the label corresponds to a biological state. The present disclosure also provides a sensor arrays for detecting biomolecules and methods of use. In some embodiments, the sensor arrays are capable of determining a disease state in a subject.

A rational design and fabrication of ZnO/Al.sub.2O.sub.3 core-shell nanowire architectures with tunable geometries (length, spacing, branching) and surface chemistry is provided. The fabricated nanowires significantly delay or even prevent marine biofouling. In some embodiments, hydrophilic nanowires can reduce the fouling coverage by up to approximately 60% after 20 days compared to planar control surfaces. The mechanism of the fouling reduction is mainly due to two geometric effects: reduced effective settlement area and mechanical cell penetration. Further, superhydrophobic nanowires can completely prevent marine algal fouling for up to 22 days. Additionally, the developed nanowire surfaces are transparent across the visible spectrum, making them applicable to windows and oceanographic sensors.

A dispersion of capsules in critical or supercritical carbon dioxide is provided. The capsules include an aqueous solution encapsulated by zeolite-templated carbon particles. Also provided is a method of making a dispersion of aqueous solution capsules. The method includes providing a medium of critical or supercritical carbon dioxide, introducing the aqueous solution into the critical or supercritical carbon dioxide medium, and introducing a zeolite-templated carbon particle into the critical or supercritical carbon dioxide medium. Associated methods of using the disclosed dispersions in hydrocarbon-bearing formations are also provided.

A multi-functional scanning probe microscopy nanoprobe may include a cantilever, a tapered structure formed on a surface of the cantilever from a first material, and a nanopillar formed on an apex of the tapered structure from a second material. One of the first and second materials may exhibit ferromagnetism and the other may have greater electrical conductivity. A method of simultaneous multi-mode operation during scanning probe microscopy may include scanning a sample with the nanoprobe in contact with the sample to produce a current measurement indicative of an electric current flowing through the sample and a height measurement indicative of a topography of the sample and, thereafter, scanning the sample with the nanoprobe oscillating about a lift height derived from the height measurement to produce a deflection measurement (e.g. phase shift) indicative of a magnetic force between the sample and the nanoprobe.

A chemical gel system having a polymer and a graphene oxide Janus nanosheets crosslinker for treating thief zones in carbonate formations. The polymer and graphene oxide Janus nanosheets crosslinker may form a crosslinked polymer gel to reduce or prevent water production via thief zones during hydrocarbon production. The graphene oxide Janus nanosheets crosslinker includes a first side having negatively charged functional groups and a second side having amines. The negatively charged functional groups may include carboxyl groups, negatively charged oxygen groups, and hydroxyl groups. Methods of reducing water production in a thief zone using the graphene oxide Janus nanosheets crosslinker and methods of manufacturing the graphene oxide Janus nanosheets crosslinker are also provided.
