Methods, systems, and devices for sampling/isolating material from cells. An exemplary system may comprise a chip including an electrode array of sampling electrodes arranged along a surface of the chip. A cell-receiving area may be located adjacent the surface of the chip. The system also may comprise a tag array of tags supported by the chip and aligned with the electrode array. Each tag of the tag array may include an identifier that is unique to the tag within the tag array. Each tag may be configured to bind nucleic acids, or a capturing agent distinct from the tag may be aligned with each sampling electrode of the electrode array to capture a protein or other analyte of interest. The system further may comprise a control circuit configured to apply an individually controllable voltage to each sampling electrode of the electrode array and measure an electrical property of the sampling electrode.

An inline filter housing with a biodegradable, hydrophilic material that operates in conjunction with a field sampling apparatus to both concentrate field sampled environmental DNA particles from water samples and to automatically preserve the captured DNA via desiccation, thus avoiding filter membrane transfer steps, chemicals or cold storage preservation requirements. The hydrophilic filter housing is capable of rapidly preserving the field sampled environmental DNA captured on the filter membrane at ambient field temperatures.
