In the present paper, we define the concept of micro-Gg-open and micro-Gg-closed sets by using micro topological space, and several properties of that set are studied, so we introduce micro-Ggγ-open set and micro-Ggϖ- closed set and denoted of micro-Gg-open set by mic-GgO(U), micro-Gg-closed set by mic-GgC(U) several theories that true and examples to the contrary are not true. We also studied a practical example of a micro-Gg-open set and a micro-Gg-closed set.
