Study of strain engineered MoS 2 and its application in lactic acid biosensors

Key Points

• This research aims to investigate how tensile strain affects the performance of MoS2 in lactic acid biosensing.
• Examined the response of MoS2 under different tensile strains.
• Measured lactic acid concentrations from 0 to 1 µM.
• Compared sensitivity of strained versus unstressed MoS2.
• Achieved nearly five times greater sensitivity at 0.29% tensile strain compared to unstressed MoS2.
• Detected lactic acid concentrations effectively within the specified range.
