Abstract: An optical scanning system adapted to scan a sample on a chip is provided. The optical scanning system includes at least one optical scanning head, at least one scanning light source, a light receiving device and a processor. Each of at least one optical scanning head includes a focusing light source, a first optical guiding structure, and a control unit. The first optical guiding structure is configured to guide the focusing light emitted from the focusing light source to travel to the sample, and the first optical guiding structure is configured to guide the at least one scanning light emitted from the at least one scanning light source to the sample to generate a secondary light. The control unit is configured to control the first optical guiding structure to keep the focusing light and at least one scanning light focusing on a surface of the chip. The light receiving device receives the secondary light and generates a scanning electronic signal.
Abstract: 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.
