Special Issue Information

Dear Colleagues,

The unique physicochemical and biological characteristics of nanomaterial/nanoparticle-based drug delivery systems are frequently utilized to increase the safety and therapeutic efficacy of encapsulated drugs by overcoming the primary limitations of conventional drug delivery systems, such as inadequate stability and solubility, lack of transmembrane transport, short circulation time and undesirable side effects. The successful advancement of nanotechnology in recent years, particularly the advent of novel nanomaterials, has yielded novel concepts and promising techniques, including targeted drug delivery toward the intended site of primary accumulation by combining therapeutic drugs with nanoparticles and targeting appropriate biological pathways. Nanoparticles have the potential to revolutionize strategies for treating vascular diseases through rational design of nano-based delivery systems for direct delivery to the bloodstream through the blood vessels, allowing for a more efficient delivery of drugs to their therapeutic target or even the diseased site, breaking down biological barriers and improving the drug's therapeutic index and particularly the development of balloon and stent delivery nanotechnologies for interventional vascular therapies. Additionally, advancements in molecular imaging have led to the emergence of the novel theranostic nanoparticles, which may carry both therapeutic and imaging properties. The field can expect significant advances in discovery, innovative technology and clinical translation over the next decade as we continue to strengthen the potential of nanotechnology for the treatment of vascular diseases. This Special Issue aims to include review and research articles that provide a comprehensive overview of the most recent attempts in the targeted delivery of nanoparticles in blood vessels and engineering of safer and more effective nanomedicines for clinical translation.

Atherosclerosis is a common form of cardiovascular disease, which is one of the most prevalent causes of death worldwide, particularly among older individuals. Surgery is the mainstay of treatment for severe stenotic lesions, though the rate of restenosis remains relatively high. Current medication therapy for atherosclerosis has limited efficacy in reversing the formation of atherosclerotic plaques. The search for new drug treatment options is imminent. Some potent medications have shown surprising therapeutic benefits in inhibiting inflammation and endothelial proliferation in plaques. Unfortunately, their use is restricted due to notable dose-dependent systemic side effects or degradation. Nevertheless, with advances in nanotechnology, an increasing number of nano-related medical applications are emerging, such as nano-drug delivery, nano-imaging, nanorobots, and so forth, which allow for restrictions on the use of novel atherosclerotic drugs to be lifted. This paper reviews new perspectives on the targeted delivery of nanoparticles to blood vessels for the treatment of atherosclerosis in both systemic and local drug delivery. In systemic drug delivery, nanoparticles inhibit drug degradation and reduce systemic toxicity through passive and active pathways. To further enhance the precise release of drugs, the localized delivery of nanoparticles can also be accomplished through blood vessel wall injection or using endovascular interventional devices coated with nanoparticles. Overall, nanotechnology holds boundless potential for the diagnosis and treatment of atherosclerotic diseases in the future. Full article
