Leukemic marker detection using a spectro-polarimetric surface plasmon resonance platform

Spectropolarimetric Surface Plasmon Resonance Sensor and the Selection of the Best Polarimetric Function

“…Assuming the accuracy level of the analyzer rotation stage is 3 10  degrees, and the noise in the intensity is 10 counts, we get a LOD of 6 10 4 . 2   RIU, which is comparable to the best newly reported works based on the spectral interrogation such as [24,31] and [37]. With more sophisticated systems this figure can be lowered by two orders of magnitudes.…”

Correlating Single-Molecule Sers Statistics to Plasmonic Nanocluster Structure and Near-Field Properties

“…With this surface coverage we generated 10 6 configurations of randonmly adsorbed molecules. For each configuration, t, the total SERS intensity can be described as the sum of the SERS intensities for N molecules: (9) For the configurations that generated a signal intensity bellow the threshold (I(t) < 0 in Eq. 9), it was assigned I(t) = 0.…”

“…Metal nanoparticles have presented an increased interest over the years due to their vast range of applicability, such as fast optical communication, 1,2 enhanced spectroscopies, 3,4 photovoltaics, [5][6][7] optical sensors [8][9][10] and photocatalysis. [11][12][13][14][15][16] All such properties are derived from the excitation of coherent surface localized electromagnetic modes, called surface plasmon.…”

A polydopamine-modified optical fiber SPR biosensor using electroless-plated gold films for immunoassays

“…The more effective the antibody immobilization is, the more antigens will be detected. Many methods, such as linking amine groups to the 1-ethyl-3-(3-(dimethylamino)propyl)-carbodiimide hydrochloride/N-hydroxysulfosuccinimide (EDC/NHS) activated carboxyl group (Liu et al, 2014b), connecting biotin to avidin, using protein A (Ko et al, 2009) or protein G (Maisonneuve et al, 2015) as a sub-layer protein, have been employed to immobilize the antibodies. Dopamine (DA), inspired by the adhesion of mussels, can be easily deposited with a controlled film thickness on almost all of the substrates by simple self-polymerization (Lee et al, 2007).…”
