Ting Deng et al.
Biosensors & bioelectronics, 21(8), 1545-1552 (2005-08-09)
A quartz crystal microbalance (QCM) sensor was proposed for the detection of small molecule biotin based on the mixed self-assembled monolayer (SAM) of thiols on gold substrate and the bioaffinity difference between an analyte (biotin) and an analogue compound (HABA)
Mehmet Cinar et al.
Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 105, 80-87 (2013-01-09)
The optimized geometrical structure, vibrational and electronic transitions, chemical shifts and nonlinear optical properties of 2-(4-hydroxyphenylazo)benzoic acid (HABA) compound were presented in this study. The ground state geometrical structure and vibrational wavenumbers were carried out by using density functional (DFT/B3LYP)
H Hofstetter et al.
Analytical biochemistry, 284(2), 354-366 (2000-08-31)
We introduce a new nonradioactive, chromogenic label based on 4-hydroxyazobenzene-2-carboxylic acid (HABA), which is suitable for bioanalytical application, e.g., detection, localization, isolation, and purification. The HABA label is superior to other systems where it is difficult to separate labeled from
