The role of nanomaterials in revolutionizing ischemic stroke treatment: Current trends and future prospects.

Ischemic stroke has a high disability rate, which leads to irreversible neuronal death. The efficacy of conventional stroke treatments, including thrombolytic and neuroprotective therapies, is constrained by a number of factors, including safety concerns and inefficient drug delivery. The advent of nanomaterials has created new avenues for stroke therapy, facilitating enhanced pharmacokinetic behavior of drugs, effective drug accumulation at the target site, augmented therapeutic efficacy, and concomitant reduction in side effects. Therefore, this paper pioneers a research approach that summarized the development trend and clinical value of nanomaterials in the field of ischemic stroke through bibliometric analysis. This review provides an overview of the pathophysiological mechanisms of stroke and examines the current research trends in the use of nanomaterials in stroke management. It encompasses a multitude of domains, including targeted drug delivery systems, biosensors for the sensitive detection of biomarkers, and neuroprotective nanotechnologies capable of traversing the blood-brain barrier. Moreover, we investigate the challenges that nanomaterials encounter in the clinical translation context, including those pertaining to biocompatibility and long-term safety. These results have provided the clinical value and limitations of nanomaterials in the diagnosis and treatment of ischemic stroke from double perspectives, thereby offering new avenues for the further development of innovative nanotherapeutic tools.
