Abstract
Magnetic-plasmonic heterodimer nanostructures synergistically present excellent magnetic and plasmonic characteristics in a unique platform as a multipurpose medium for recently invented biomedical applications, such as magnetic hyperthermia, photothermal therapy, drug delivery, bioimaging, and biosensing. In this review, we briefly outline the less-known aspects of heterodimers, including electronic composition, interfacial morphology, critical properties, and present concrete examples of recent progress in synthesis and applications. With a focus on emerging features and performance of heterodimers in biomedical applications, this review provides a comprehensive perspective of novel achievements and suggests a fruitful framework for future research.
Highlights
Aqueous colloids of heterodimer nanoparticles are a fascinating class of multimodal hybrid structures, which have appeared in the last decade and increasingly attracted many attentions
Hyperthermia cancer treatment, magnetic resonance imaging (MRI), and magnetically targeted drug delivery have been chosen for the magnetic part, and photothermal therapy and bioimaging were chosen for the plasmonic part
Plasmonic characteristics are associated to the response of nanoparticles to electromagnetic radiation in the specific wavelength ranges of ultra-violet (UV), visible, and near infra-red (NIR) light, which are used for different biomedical applications, including photothermal therapy and imaging approaches [69,70,71]
Summary
Aqueous colloids of heterodimer nanoparticles are a fascinating class of multimodal hybrid structures, which have appeared in the last decade and increasingly attracted many attentions. The positive roles of different magnetic-plasmonic heterodimers for various biomedical diagnostic and therapeutic treatments have been reported, including magnetic resonance imaging (MRI) [46,47,48], cellular uptake [49,50,51], plasmon imaging [52,53], X-ray computed tomography (CT) [54], positron emission tomography (PET) [55], photothermal therapy (PTT) [56–.
