Cu1.94S–MnS dimeric nanoheterostructures with bifunctions: localized surface plasmon resonance and magnetism†
Abstract
Cu1.94S–MnS dimeric nanoheterostructures are fabricated by employing Cu1.94S nanoplates as precursors. By managing the heterogrowth of MnS, the localized surface plasmon resonance wavelength of Cu1.94S can be optimized to 1323 nm, which makes this nanoheterostructure applicable as a light absorbing agent for photothermal therapy. Meanwhile, Mn2+ ions enable the nanoheterostructures to exhibit paramagnetic behavior at room temperature, indicating their possible application as a magnetic contrast agent for magnetic resonant imaging. This kind of bifunctional material is a potential candidate for the so-called “theranostic agent”, which is of great significance in biomedical application.
