چکیده
Volume 3 • Issue 4 • 1000e108 J Nanomed Nanotechol ISSN:2157-7439 JNMNT an open access journal For centuries, metals and alloys have been used in substitution for anatomical structures owing to their extraordinary mechanical properties [1]. Type 316L Stainless Steel (SS) is known to be widely used for implantation purposes in orthopedic surgery due to its corrosion resistance, effective cost and superior mechanical properties [1,2]. However, several incidences of failures involving type 316L SS have been occurred which released the metal ions into tissues [1] and blood stream surrounding the implants, thus causing histological changes of the local tissue by direct toxic effects or local hypersensitivity reaction [3]. It is highly probable that electrophoretically deposited Multiwall Carbon Nanotubes (MWCNTs) and Hydroxyapatite (HA) on type 316L SS could minimize this limitation, and further investigation of its corrosion behavior using in vitro electrochemical techniques [1,4] may confirm the acceptability of modified SS as an effective biomaterial to be used as orthopedic implants.
