Various plants and fruit extract can be used to synthesize MgONPs to find a eco-friendly way of synthesis. Detailed mechanistic study of influence in seed germination by MgONPs can be elucidate and a study behind antimicrobial activity yet to be explored by using MgONPs. MgONPs may be used to examine the effect on other clinically and industrially important gene expression in vivo and vitro. Toxicity profile of MgONPs in vivo and vitro have notable attention.
