Analysis of protein interactions on protein arrays by a novel spectral surface plasmon resonance imaging

Performance enhancement of polyaniline-based polymeric wire biosensor

“…Several biosensors were developed based on the electrochemical, optical, and piezoelectric detection principles (Kim et al, 2000;Yuk et al, 2006;Vaughan et al, 2001). A disposable polyaniline-based biosensor measuring an electrical response by using conducting polyaniline was developed to fulfill the above-mentioned demands (Muhammad-Tahir and Alocilja, 2003a).…”

Highly Sensitive Local Surface Plasmon Resonance in Anisotropic Au Nanoparticles Deposited on Nanofibers

“…The resonance wavelength of the LPR sensitively varies with the dielectric condition in the surroundings of a nanoparticle. It has been applied to the transducer of a label-free biosensor that detects the affinity between biomaterials such as a virus, specific chemicals, DNAs, and proteins without fluorescent labeling [9][10][11][12][13][14][15][16][17]. These LPR characteristics can be utilized with a single nanoparticle [18,19]; then the nanoparticle with the LPR was often expected to be an in vivo nanosensor or an in vivo nanosensitizer detecting biochemical materials in living cells or animals [20,21].…”

Recent advances in surface plasmon resonance imaging: detection speed, sensitivity, and portability

“…In recent years, lots of efforts have been spent to improve the sensitivity as well as the throughput. Yuk et al [26] introduced an SPRi sensor for the investigation of protein interactions on arrays, where, in addition to the calculation of the resonance wavelength from the SPR reflectivity spectra, the authors also incorporated the position control. With these arrangements, they could quantitatively analyze the specific binding of anti-Rac1 and anti-RhoA to Rac1 and RhoA on the protein arrays.…”
