Introduction: Recent advances in nanoscience and biomedicine have attracted tremendous attention over the past decade to design and construct multifunctional nanoparticles that combine targeting, therapeutic, and diagnostic functions with a single platform to overcome the problems of conventional techniques for diagnosis and therapy with minimal toxicity. Materials ...
objective: maintaining the health of oral tissues is a major goal in dentistry. however, limitations in dental materials, instruments, procedures and medications prevent achievement of this goal. advances in nanotechnology have paved the way to approach this goal. this study reviews the advances on nanotechnology in dentistry. review of literatures: in this review study, google scholar, pubmed,...
There is considerable interest in developing nanohybrids of imaging contrast agents and drugs for image-guided drug delivery. We have developed a strategy of utilizing manganese (Mn) to enhance the nano-encapsulation of arsenic trioxide (ATO). Formation of arsenite (As(3+))-Mn precipitates in liposomes generates magnetic susceptibility effects, reflected as dark contrast on T2-weighted MRI. Int...
Although many breast and lung cancers overexpress human epidermal growth factor receptor-2 (HER-2), no methods currently exist for effective and early detection of HER-2-positive cancers. To address this issue, we designed and synthesized dendrimer-based novel nano-imaging agents that contain gold nanoparticles (AuNPs) and gadolinium (Gd), conjugated with the humanized anti-HER-2 antibody (Herc...
A multimodal, β-amyloid-targeted contrast agent was synthesized and studied in vitro. The agent has a higher relaxivity than a clinically approved contrast agent and interacts with β-amyloid aggregates producing changes in relaxation rate and fluorescence emission.
