Abstract

Functionalized nanotube arrays, sensors, and related methods of detecting target compounds are presented. A functionalized nanotube array (235) can include a plurality of metal oxide nanotubes (240). The metal oxide nanotubes (240) can be formed of a metal oxide and can have an interior or exterior surface that is optionally functionalized with at least one metal ion. These metal nanotubes (240) can be used in a sensor (200) for detecting target compounds such as volatile organic compounds, and biomarkers in a fluid environment. The sensor (200) can further include a power source (245) configured to apply a voltage to the nanotube array (235) and a current sensor (250) configured to monitor and detect changes in a response current which varies upon binding with the target compounds.

Dependent claims

A sensor for detecting a volatile organic compound, comprising:

a nanotube array including a plurality of functionalized metal oxide nanotubes, the metal oxide nanotubes being formed of a metal oxide and having at least one of an interior and exterior surface capable of binding with the volatile organic compound, said surface being functionalized with at least one metal ion selected from the group consisting of Fe2+, Pb2+, Fe3+, Cr3+, Mn3+, Mn4+, As4+, Pt4+, Pd2+, Pd4+, and combinations thereof;
a power source configured to apply a voltage to the nanotube array;
and
a current sensor configured to monitor and detect changes in a response current which varies upon binding with the volatile organic compound.
