Abstract:A low-cost and disposable graphene polylactic (G-PLA) 3D-printed electrode modified with gold particles (AuPs) was explored to detect the cDNA of SARS-CoV-2 and creatinine, a potential biomarker for COVID-19. For that, a simple, non-enzymatic electrochemical sensor, based on a Au-modified G-PLA platform was applied. The AuPs deposited on the electrode were involved in a complexation reaction with creatinine, resulting in a decrease in the analytical response, and thus providing a fast and simple electroanalyti… Show more
“…The use of PLA with graphene has been reported in many studies. [43][44][45][46][47][48] It has been reported that most of them used dimethylformamide (DMF), NaOH, and sulfuric acid treatment for the surface modication. Table 1 shows the different types of materials that are used in 3D printing with their surface modication techniques and applications.…”
Three-dimensional (3D) printing in tissue engineering and biosensing of analytes by using biocompatible material or modifying the surface structure is an upcoming area of study. This review discusses three common...
