Graphene as a photothermal actuator for control of lipid mesophase structure

摘要: The optical density of pristine graphene is high and broad in the near infrared region electromagnetic spectrum positioning this material as a highly efficient photothermal agent for vivo applications. In study, surfactant assisted exfoliated was incorporated within bulk lipid samples varying types: glyceryl monoether, monooleate phytantriol. sheets did not disrupt packing liquid crystals while being sufficiently intimate contact to provide localized heating induce phase transitions. progressions induced through using NIR irradiation entrained particles crystal were studied SAXS confirmed polarized microscopy. Increases apparent temperature experienced by matrix up 50 °C observed establishing versus calibration curve allowing situ measurements. studies demonstrate potential use actuator across range based systems interest controlled drug delivery.
