Sulfur is an important element with many practical applications when
present as nanoparticles. Nanosize sulfur particles also have many important
applications like in pharmaceuticals, medicine, synthesis of nano-composites for
lithium batteries, modification of carbon nano tubes [1]. Different methods were
used for nano-sized particle synthesis; among those, chemical precipitation,
electrochemical method, micro emulsion technique, composing of oil, surfactant,
co-surfactant, aqueous phases with the specific compositions and ultrasonic
treatment of sulfur-cystine solution [2]. In this work sulfur nanoparticles (S NPs)
were prepared by a quick precipitation method with and without using a
surfactant to stabilize the formed S NPs.
The synthesized S NPs were characterized by XRD, SEM and TEM in order to
confirm their sizes and structures.
Application of nanotechnology is suggested for diagnosis and treatment of cancer
[3]. The anticancer activity of the prepared S NPs has been tested on various types
of cancer cell clones including leukemia, kidney and colon cancers.
The desired S NPs revealed a high
promising activity and selectivity
toward killing kidney cancer .
