Materials in the functionalization layer may be deposited on the NTFET using various different methods, depending on the material to be deposited. It should be understood that mixtures, alloys and composites of the materials may also be included. For many materials, ALD methodology is known which is suitable for depositing thin, uniform layers or coatings, which may be controlled to deposit on selected portions of a device, and which may be employed to produce mixtures or multi-layer coatings also. See, for example, U.S. Ser. No. 11/588,845 filed Oct. 26, 2006 (published 2008-0021339), entitled “Anesthesia Monitor, Capacitance Nanosensors and Dynamic Sensor Sampling Method”, which is incorporated by reference.
The nanoelectronic sensors having aspects of the invention are inherently suitable to array configurations, such as may be employed in the multi-analyte integrated breath analysis system described herein. These sensors and sensor arrays can be fabricated by a range of known manufacturing technologies (see U.S. patent application Ser. No. 10/846,072 entitled “Flexible Nanotube Transistors” which is incorporated herein). One preferred approach is to use the wafer processing technology developed for the semiconductor electronics industry. This approach not only permits many sensors to be made on as single chip, but permits sensors of different functional types and different architectures to be produced simultaneously on a common substrate, using appropriate photolithographic techniques, masking, controlled etching, micro-machining, vapor deposition, “ink jet” type chemical application and circuit printing, and the like, to produce the elements of the various sensor devices and associated circuitry.
See additional description in of a particular NO to NO2 conversion device having aspects of the invention below with respect to FIG. 9
In one embodiment having aspects of the invention, inhaled air may be passed through a “scrubber” device to remove environmental NO (and/or any other selected substance, such as CO2, NOx and the like) prior to administration to a patient or test subject. During or after a collection of a subsequent exhaled air sample, the sample may be passed through an conversion device to oxidize all or a portion of the NO to NO2. Optionally, the exhaled sample may be passed through one or more filter or absorber devices to remove particulates, water vapor, atomized fluids, and/or gasses such as CO2 and the like.
FIG. 7 illustrates the operation one exemplary embodiment having aspects of the invention, and the effect for an electron donating (NH3) and electron withdrawing (NO2) species on the NTFET transistor device characteristic, believed to be the result of charge transfer between the molecular species and the carbon nanotubes. In this example, the NTFET devices were fabricated using SWNTs grown by chemical vapor deposition (CVD) on 200 nm of silicon dioxide on doped silicon from iron nanoparticles with methane/hydrogen gas mixture at 900° C. Electrical leads were patterned on top of the nanotubes from titanium films 35 nm thick capped with gold layers 5 nm thick, with a spacing of 0.75 μm between source and drain. The devices were contact-passivated with a liftoff-patterned SiO layer, which was extended over the leads and for several hundred nanometers on either side.
For further description, see (a) U.S. Ser. No. 10/656,898 filed Sep. 5, 2003 (published 2005-0279,987), entitled “Polymer Recognition Layers For Nanostructure Sensor Devices”; (b) A. Star, K. Bradley, J.-C. P. Gabriel, G. Grüner, “Nano-Electronic Sensors: Chemical Detection Using Carbon Nanotubes”, Pol. Mater.: Sci. Eng. 89, pp 204 (2003); and (c) U.S. Ser. No. 11/259,414 filed Oct. 25, 2005 (published 2006-0228723) entitled “Systems And Method For Electronic Detection Of Biomolecules”; each of which is incorporated by reference.
In one embodiment of a converter configured for breath analysis, a small amount of Pt is deposited on quartz wool, and is loosely packed into one or more suitable enclosures (e.g., an inert tube such as borosilicate glass, PTFE, or the like). In one example, about 0.2-0.4 g total weight of wool plus Pt was disposed in a tube of about 10″ length and ⅛-¼″ inner diameter. The wool was arranged to take up about 1-2″ of length in the tube, and positioned about ¼ of the way from one end. Alternatively, a different matrix, e.g. mesh, made of quartz or SiO2 can be used as substrate. Various approaches, including wet chemistry, electroplating, and atomic layer deposition can be applied for depositing a coating layer or particles of Pt (or other catalytic material).
