Colorimetric/fluorescent dual-module bivalent aptasensor for kanamycin detection based on silver nanoparticles and silver nanoclusters

Key Points

• Kanamycin detection is achieved using a dual-module aptasensor based on silver nanoparticles and silver nanoclusters.
• The aptasensor shows a high sensitivity with a detection limit of 0.1 nM for kanamycin in various solutions.
• The approach utilizes colorimetric and fluorescent methods to enhance the detection mechanisms of the aptasensor.
• This method may enable faster and more accurate tests for kanamycin, providing a useful tool in clinical settings.
