    摘要: A biochip including a DNA chip and a protein chip and a method for patterning and measuring biomaterial of the same are disclosed. The method for patterning a biomaterial of the biochip including a reflecting layer and an active layer on a substrate includes the steps of: rotating the biochip; successively irradiating pulse type laser beams to the rotating biochip to activate predetermined regions of the active layer; and fixing a biomaterial pattern on the activated predetermined regions. A method for measuring the patterned biomaterial includes the steps of: reacting a biomaterial labeled with at least one dye material with the biochip; rotating the biochip reacted with at least one biomaterial; successively irradiating laser beams to the rotating biochip; and detecting and processing light derived from the biochip as a result of reaction of the biomaterial to measure the biomaterial. Thus, the biochip having reliability and high packing density can be fabricated at low cost and the biomaterial of the biochip can be measured at high speed without using expensive equipments.
