Studies of chitosan thionine-reduced graphene oxide nanocomposite as electrode for ganoderma disease biosensor / Muhammad Aidil Ibrahim

Biosensor is a device that applies biological components to detect target substances involving electrochemistry. In this research, DNA-based biosensor was developed to sensitively detect Ganoderma boninense (GB) which is a fungus that causes basal stem rot to oil palm trees. The DNA-based biosensor...
