Transition metal dichalcogenide (TMD) represented by molybdenum disulfide (MoS 2) is a
promising platform for versatile applications in biosensing. The semiconducting properties of
MoS 2 coupled with its large surface area allows for highly sensitive detection of external
environments. Although chemical vapor deposition (CVD) is a promising method for
synthesizing large and high quality MoS 2, optical properties of CVD-grown MoS 2 under

Abstract
Transition metal dichalcogenide (TMD) represented by molybdenum disulfide (MoS 2) is a promising platform for versatile applications in biosensing. The semiconducting properties of MoS 2 coupled with its large surface area allows for highly sensitive detection of external environments. Although chemical vapor deposition (CVD) is a promising method for synthesizing large and high quality MoS 2, optical properties of CVD-grown MoS 2 under physiological solution is not clear. Furthermore, understanding of the pH effect on its optical properties is still limited.
