FIG. 1.

Principle of differential surface stress measurement.

FIG. 2.

Optical circuit of differential surface stress sensor. MLA1 (diameter of and pitch of ) collimates beams and delivers to MLA2 (diameter of and pitch of ). Bidirectional couplers were used to split the reflected beams and direct one component toward photodetectors to measure the intensity of reflected beams.

FIG. 3.

Differential surface stress change and corresponding cantilever deflections measured for the introduction of hybridization buffer with no oligonucleotide (buffer); poly(T) in hybridization buffer (specific binding); poly(A) in hybridization buffer (nonspecific binding).
