Aravind I, Wang Y, Cai Z, Li R, Shahriar R, Gibson G, et al.
J Chem Phys . 2024 Jul; 161(3). PMID: 39007387
We have used surface plasmon resonant metal gratings to induce and probe the dielectric response (i.e., electro-optic modulation) of ionic liquids (ILs) at electrode interfaces. Here, the cross-plane electric field...

Davino M, McManus E, Helming N, Cheng C, Mool G, Rodnova Z, et al.
Rev Sci Instrum . 2023 Feb; 94(1):013303. PMID: 36725611
Since their inception, velocity map imaging (VMI) techniques have received continued interest in their expansion from 2D to 3D momentum measurements through either reconstructive or direct methods. Recently, much work...

Cady N, Tokranova N, Minor A, Nikvand N, Strle K, Lee W, et al.
Biosens Bioelectron . 2020 Oct; 171:112679. PMID: 33069957
The 2019 SARS CoV-2 (COVID-19) pandemic has illustrated the need for rapid and accurate diagnostic tests. In this work, a multiplexed grating-coupled fluorescent plasmonics (GC-FP) biosensor platform was used to...

Wang Y, Aravind I, Cai Z, Shen L, Gibson G, Chen J, et al.
ACS Appl Mater Interfaces . 2020 Mar; 12(15):17459-17465. PMID: 32212673
We demonstrate the hot electron injection of photoexcited carriers in an Ag-based plasmon resonant grating structure. By varying the incident angle of irradiation, sharp dips are observed in the reflectance...

Wang Y, Shen L, Wang Y, Hou B, Gibson G, Poudel N, et al.
Faraday Discuss . 2019 May; 214(0):325-339. PMID: 31049541
Plasmon resonant grating structures provide an effective platform for distinguishing between the effects of plasmon resonant excitation and bulk metal absorption via interband transitions. By simply rotating the polarization of...

Khosravi S, Bishop M, LaFountain A, Turner D, Gibson G, Frank H, et al.
J Phys Chem B . 2018 Nov; 122(48):10872-10879. PMID: 30387609
Steady-state absorption, transient absorption, and transient grating spectroscopies were employed to elucidate the role of a conjugated carbonyl group in the photophysics of carotenoids. Spheroidenone and spheroidene have similar molecular...

Mollahosseini M, Karunaratne E, Gibson G, Gascon J, Papadimitrakopoulos F
J Am Chem Soc . 2016 Apr; 138(18):5904-15. PMID: 27127896
One of the greatest challenges with single-walled carbon nanotube (SWNT) photovoltaics and nanostructured devices is maintaining the nanotubes in their pristine state (i.e., devoid of aggregation and inhomogeneous doping) so...

Magdaong N, LaFountain A, Hacking K, Niedzwiedzki D, Gibson G, Cogdell R, et al.
Photosynth Res . 2015 Jun; 127(2):171-87. PMID: 26048106
Photosynthetic organisms produce a vast array of spectral forms of antenna pigment-protein complexes to harvest solar energy and also to adapt to growth under the variable environmental conditions of light...

Yuk J, Gibson G, Rice J, Guignon E, Lynes M
Analyst . 2012 Apr; 137(11):2574-81. PMID: 22498719
We have developed a novel dual mode immunoassay platform that combines the advantages of real-time, label free measurement of surface plasmon resonance (SPR) and the highly directional surface plasmon-coupled emission...
