Abstract. Magnetite is an iron oxide that has been extensively investigated for its utilization in the development of drug delivery nanocarriers. Generally, magnetite nanoparticles are obtained through the chemical route of co-precipitation. However, since the outcome properties of the resulted nanoparticles are limited in terms of possibility to control the size and size distribution and to ensure the reproducibility of the synthesis process, unconventional synthesis routes are constantly investigated. Specifically, the microwave-assisted hydrothermal method represents an alternative with tremendous potential owing to the possibility of varying the treatment parameters, i.e., pressure, temperature, time. Thus, the present study aimed to investigate the influence of time and temperature upon the structural and physico-chemical properties of magnetite nanoparticles.

Keywords: magnetite nanoparticles, microwave-assisted hydrothermal method, drug delivery
