ACS Appl Mater Interfaces. 2012 Aug;4(8):4251-8. doi: 10.1021/am300961d. Epub 2012 Aug 01.

Aligned arrays of silicon nanowires (aa-Si NWs) allow the exploitation of Si NWs in a scalable way. Previous studies explored the influence of the Si NWs' number, doping density, and diameter on the related electrical performance. Nevertheless, the origin...

Systematic cross-linking changes within a self-assembled monolayer in a nanogap junction: a tool for investigating the intermolecular electronic coupling.

Journal of the American Chemical Society

Paska Y, Haick H.
PMID: 20088587
J Am Chem Soc. 2010 Feb 17;132(6):1774-5. doi: 10.1021/ja910126s.

Here, we show that a controllable cross-linking within a self-assembled monolayer can be used as a tool for investigating the (lateral) intermolecular coupling between adjacent organic molecules. We draw this conclusion based on macroscopic electrical experiments with self-assembled hexyltrichlorosilane...

Sensor Arrays Based on Polycyclic Aromatic Hydrocarbons: Chemiresistors versus Quartz-Crystal Microbalance.

ACS applied materials & interfaces

Bachar N, Liberman L, Muallem F, Feng X, Müllen K, Haick H.

ACS Appl Mater Interfaces. 2013 Nov 27;5(22):11641-53. doi: 10.1021/am403067t. Epub 2013 Nov 06.

Arrays of broadly cross-reactive sensors are key elements of smart, self-training sensing systems. Chemically sensitive resistors and quartz-crystal microbalance (QCM) sensors are attractive for sensing applications that involve detection and classification of volatile organic compounds (VOCs) in the gas...

A Highly Sensitive Diketopyrrolopyrrole-Based Ambipolar Transistor for Selective Detection and Discrimination of Xylene Isomers.

Advanced materials (Deerfield Beach, Fla.)

Wang B, Huynh TP, Wu W, Hayek N, Do TT, Cancilla JC, Torrecilla JS, Nahid MM, Colwell JM, Gazit OM, Puniredd SR, McNeill CR, Sonar P, Haick H.
PMID: 26996398
Adv Mater. 2016 Jun;28(21):4012-8. doi: 10.1002/adma.201505641. Epub 2016 Mar 21.

An ambipolar poly(diketopyrrolopyrrole-terthiophene)-based field-effect transistor (FET) sensitively detects xylene isomers at low ppm levels with multiple sensing features. Combined with pattern-recognition algorithms, a sole ambipolar FET sensor, rather than arrays of sensors, can discriminate highly similar xylene structural isomers...
