A report from Shahid Bahonar University of Kerman in Iran discusses research findings on cancer. The researchers developed a carbon paste electrode modified with a nanocomposite containing graphene oxide and metal organic framework-235 (MOF-235/GO/CPE) for the electrochemical detection of the anticancer drug doxorubicin (DOX). The sensor showed good sensitivity and selectivity for DOX, with a detection limit of 0.005 μM and a wide dynamic concentration range. The researchers also explored the use of the sensor for the determination of DOX in the presence of dacarbazine (DCB). The research concluded that the sensor demonstrated satisfactory recoveries and was effective for the detection of DOX and DCB in real samples. [Extracted from the article]
