Calcium Oxide Nanoparticles

CaO is a good example of naturally abundant earth metal oxides. CaO nanoparticles have spherical or faceted high surface area, also they are magnetic nanostructured particles. Calcium oxide (CaO), commonly known as burnt lime or quicklime, is an alkaline earth metal oxide. Calcium is a Block S, Group 2, Period 4 element, while oxygen is a Block P, Period 2 element. Cao nanoparticles can be prepared by various techniques such as sol-gel method, precipitation, hydrogen plasma-metal reaction, sonochemical synthesis, thermal-decomposition method etc. Calcium Oxide (CaO) nanoparticles have found several applications such as in catalysis, adsorption, water purification and also as antibacterial agents. CaO is a material of particular interest as it is regarded as a safe material to human beings and animals. CaO NPs possess excellent antimicrobial potential and capability to inactivate microbial endotoxin. Due to CaO NPs unique structural and optical properties, they can be used as a potential drug delivery agent, in photodynamic therapy (PDT), photo-thermal therapy (PTT), and synaphic delivery of chemotherapeutic agents. Also, due to its good porosity, it finds its part in storage systems and its biocompatibility earns it a good value in drug delivery and gene transfection.
