Graphene-Based Biosensor to Detect Creatinine at Trace Levels

Reliable and accurate creatinine analysis is critical for the timely diagnosis and treatment of individuals with renal disease. In a study published in the journal Biosensors and Bioelectronics, an innovative biosensor based on graphene nanoplatelet/polydopamine molecularly imprinted polymer is presented for trace-level creatinine detection in a variety of bodily fluids.​​​​​​​
