Appl. No.:

16/076077
Inventors:

- Spring TX, US
Aleksandr POLYAKOV - Palo Alto CA, US
Anita ROGACS - Palo Alto CA, US
Assignee:

HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P. - Houston TX
International Classification:

G01N 21/65
G01N 21/552
Abstract:

A surface enhanced infrared absorption stage may include a substrate, a static island extending from the substrate and a movable nano finger extending from the substrate. The static island may have a plasmonically active island cap and a dimension parallel to the substrate of at least one micrometer. The movable nano finger may be aligned with the dimension. The movable nano finger may have a plasmonicaly active finger cap closable to less than or equal to 5 nm of the island cap.

Filed:

Dec 17, 2020
Appl. No.:

17/125914
Inventors:

- Spring TX, US
Anita Rogacs - San Diego CA, US
Assignee:

Hewlett-Packard Development Company, L.P. - Spring TX
International Classification:

C12M 1/34
B01D 53/32
B01D 67/00
B01D 69/14
G01N 33/543
C12M 1/04
Abstract:

An apparatus may include a lower chamber to contain a culture that emits volatile organic compounds, an upper chamber, a first sensor within the upper chamber, a second sensor within the upper chamber in a transport selector. The second sensor may be different than the first sensor so as to sense volatile organic compounds differently than the first sensor. The transport selector is to transport a selected portion of the volatile organic compounds emitted from the lower chamber to the first sensor and a second portion of the volatile organic compounds emitted from the lower chamber to the second sensor.
