Metal oxides are an extraordinary class of materials that have found wide applicability for a number of century-defining technologies (e.g. flat-panel display, capacitors and energy storage) mainly due to their dielectric properties and chemical inertness. Doping, defect engineering, quantum confinement and extending to clusters, ternary or high entropy oxides can create disruptive materials with new or improved properties. Atmospheric pressure microplasmas represent a viable synthesis platform to achieve exceptional tuning capability therefore achieving an exquisite control of the size, composition and defects of metal oxide nanoparticles. In this contribution we will report on the synthesis and properties of metal oxide nanoparticles spanning a wide range of chemical compositions including oxides from Ca, Co, Cu, Mn, Mo, Ni, Sn, and Zn. We will report on the technological and application opportunities as well as on the fundamental aspects that relate to the synthesis methodologies and material structural properties. Future prospects involving complex oxides will also be presented and discussed.<br/><br/><b>References</b><br/>[1] Ni C<i> et al.</i> Green Chemistry 20 (2018) 2101<br/>[2] Wagner A J<i> et al.</i> Physical Review E 80 (2009) 065401R<br/>[3] McGlynn R<i> et al.</i> Solar Energy 203 (2020) 37<br/>[4] Velusamy T<i> et al.</i> Plasma Processes & Polymers 14 (2017) 1600224<br/>[5] Nolan H et al.
