The invention provides methods for the detection, quantification, identification and structural analysis of one or more molecules. Mass spectrometry (MS) is not a universal detector as all molecules do not ionize equally well leading to poor signal to quantity information. MS can be optimized to identify the specific mass of a binding component when the presence of a material is known. Colorimetric resonant reflectance optical sensors provide a universal mass detector in that nearly all biological masses give equally proportional signals. The combined methods allow selection and or detection with quantification of all masses binding to the sensor with the ability to identify specific molecules by their individual masses and structure analyses.

An optical biological detector is able to bind specific targeted bacterial cells by stamping an antibody grating pattern onto a silicon surface. The antibody grating alone produces insignificant optical diffraction, but upon immunocapture of the targeted cells, the optical phase change produces a diffraction pattern. Micro-contact printing provides a method for placing the antibody grating pattern directly onto a substrate surface with no additional processes or binding chemicals. Antibodies or other biologically active material may be stamped directly onto clean native oxide silicon substrates with no other chemical surface treatments. Direct binding of the antibodies to the silicon occurs in a way that still allows them to function and selectively bind antigen. The performance of the sensor was evaluated by capturing Escherichia coli O157:H7 cells on the antibody-stamped lines and measuring the intensity of the first order diffraction beam resulting from the attachment of cells. The diffraction intensity increases in proportion to the cell density bound on the surface.

The present disclosure relates to compositions and methods of modulating inflammatory and immune responses through binding of SAA to TLR2 in a subject (e.g., human, non-human primate, rodent, etc.), and compositions and methods for screening TLR2 agonists and antagonists. In the studies described herein, a potential role of SAA in neutrophilia was investigated and the results demonstrated that SAA is a potent inducer for macrophage secretion of G-CSF, which leads to neutrophilia in mice.
