1)Micro array is a laboratory tool used to analyze large numbers of genes or proteins at one time. In a microarray, biologic molecules such as DNA, RNA, or protein are placed in a pattern onto a surface such as a glass slide. Other substances are added to these slides to detect specific patterns of molecules.
2)Microarray is currently used in three broad areas: medical diagnosis and treatment, biotechnological and other researches, as well as crime and security.
3)Microarray is one of the most recent advances being used for cancer research; it provides assistance in pharmacological approach to treat various diseases including oral lesions.
