Biosensor and Method of Forming Probe on Solid Surface of Biosensor

A biosensors and a method of forming a probe on a solid surface of a biosensor are disclosed and the method includes the following steps. A unit (a nucleotide or an amino acid) capped with a protecting group is covalently bonded on the solid surface of one of a plurality of sensor cells of the biosensor. At least one cycle of the following steps is performed until a desired number of units is formed: irradiating the one of the plurality of sensor cells, so as to remove the protecting group of the unit; and binding a unit capped with the protecting group to the de-protected unit. The one of the plurality of sensor cells is irradiated to remove the protecting group.

Partially Neutral Single-Stranded Oligonucleotide

The present invention relates to a detection unit comprising a solid surface and a partially neutral single-stranded oligonucleotide comprising a first portion. The first portion is attached to the solid surface; the length of the first portion is about 50% of the total length of the partially neutral single-stranded oligonucleotide; and the first portion comprises at least one neutral nucleotide and at least one unmodified nucleotide. The invention improves the detection sensitivity and accuracy of the detection of biomolecules.
