Purpose: Theranostic nanoplatforms are promising approaches for diagnosis and treatment. Here, we report a drug-loaded nanomicelle system with biocleavable gadolinium (Gd) chelates as a multifunctional biodegradable agent for simultaneous magnetic resonance imaging (MRI) and drug delivery.
Methods: Self-assembled nanomicelles based on stearic acid-grafted chitooligosaccharide were utilized as vehicles.
