Abstract

The selective and quantitative detection of biocomponents is greatly requested in biomedical applications and clinical diagnostics. Many traditional magnetic materials are not suitable for the ever-increasing demands of these processes. The push for a new generation of microscale sensors for bioapplications continues to challenge the materials science community to develop novel nanostructures that are suitable for such purposes. The principal requirements of a new generation of nanomaterials for sensor applications are based on well-known demands: high sensitivity, small size, low power consumption, stability, quick response, resistance to aggressive media, low price, and easy operation by nonskilled personnel. There are different types of magnetic effects capable of creating sensors for biology, medicine, and drug delivery, including magnetoresistance, spin valves, Hall and inductive effects, and giant magnetoimpedance. The present goal is to design nanomaterials both for magnetic markers and sensitive elements as synergetic pairs working in one device with adjusted characteristics of both materials. Synthetic approaches using the advantages of simulation methods and synthetic materials mimicking natural tissue properties can be useful, as can the further development of modeling strategies for magnetic nanostructures.

Abstract

In recent years, there have been outstanding achievements in stroke diagnosis and care. Our better understanding of the pathophysiological mechanisms and the advances in neuro-imaging have enabled us to diagnose stroke syndromes with remarkable precision and uncover underlying vessel pathologies that can be directly correlated to the stroke event. Within a short period of time, mechanical thrombectomy became the standard of care for patients with large vessel occlusions and symptom onset up to 24 hours, while other recent trials also suggest the use of perfusion imaging to guide intravenous thrombolysis in the extended time window. In this Special Issue, we will also extensively discuss relevant topics on secondary stroke prevention, including the prompt use of nonvitamin k oral anticoagulants and the potential effect of reversal agents in patients with intracerebral hemorrhage related to their use. We will also delineate treatment options for stroke patients with indication for long-term anticoagulation and high bleeding risk. Finally, a particular mention will be made for young patients with stroke, the extent of the diagnostic work-up, and the selection of those who would benefit from patent foramen ovale closure.
