An energy-based model is presented to establish the bending deformation of microcantilever beams induced by single-stranded DNA (ssDNA) adsorption. The total free energy of the DNA-microcantilever sensor was obtained by considering the excluded-volume energy and the polymer stretching energy of DNA chains from mean-field theory. and the mechanical energy of three non-biological layers... https://www.bekindtopets.com/hot-save-Well-Rite-WR-240-Well-Pressure-Storage-Tank-Steel-81-Gal-great-buy/
