Abstract

Two dimensional MoS2 with graphene-like layered structure have been already reported its promising potential for biomedical applications of theranostic agents However MoS2 nanosheets have suffered from the wide distribution of their size due to the manner of preparation resulting in the presence of the inevitable irregular shape Until now it have been plagued with no further controllable shapes of MoS2 morphology that was explored for biomedical applications except layered structure We develop a zero dimensional hollow silica/MoS2 hybrid nanoshells (h-SiO2/MoS2) as theranostic agents Starting with SiO2 nanosphere as a template through a hydrothermal reaction of Na2MoO4 and thiourea in the acidic environment formed MoS3 on the surface of SiO2 Subsequently the pyrolysis transformed to MoS2 followed by an etching procedure for using PBS (pH = 10) to generate a hollow structure The h-SiO2/MoS2 also acts as echogenic source to give ultrasound imaging that is not seen using layered structure What’s more it is a successful course of experiment that can control the particle size and shell thickness of h-SiO2/MoS2 which presents the effective photothermal therapy and the diverse echogenic effect
