Special Issue Information

Dear Colleagues,

Advances in magnetic and optical sensors have revolutionized the fields of healthcare, medical diagnostics, and bioscience applications. These sensors play a pivotal role in enabling point-of-care testing, offering unprecedented opportunities for rapid and accurate diagnosis, monitoring, and treatment of various diseases. To explore the latest breakthroughs in this exciting field, we invite researchers and practitioners to contribute their original research papers to a Special Issue on “Magnetic and Optical Sensors for Healthcare, Medical, and Bioscience Applications”.

Magnetic sensors have emerged as powerful tools in healthcare and bioscience applications. Their ability to detect and quantify biomarkers and analytes in complex biological samples has opened new avenues for disease diagnosis and monitoring. Additionally, optical sensors offer non-invasive and high-sensitivity detection methods, facilitating a real-time analysis of biological parameters. The integration of magnetic and optical sensing technologies has shown great promise in enhancing the accuracy, sensitivity, and specificity of diagnostic assays.

This Special Issue aims to showcase recent advancements in magnetic and optical sensor technologies and their applications in healthcare, medical diagnostics, and bioscience. We invite submissions on topics including, but not limited to:

  • Magnetic biosensors for disease detection and monitoring.
  • Optical biosensors for real-time analysis of biomarkers.
  • Point-of-care sensing devices for rapid diagnostics.
  • Magnetic separation techniques for sample preparation.
  • Microfluidic channel systems for enhanced sensor performance.
  • Novel sensing methodologies and sensor fabrication techniques.
  • Integration of magnetic and optical sensors for multiplexed analysis.

We encourage authors to present original research, review articles, and innovative methodologies that address the challenges and opportunities in the development and application of magnetic and optical sensors in healthcare and bioscience. Submitted papers will undergo a rigorous peer-review process to ensure high quality and relevance to the theme of the Special Issue.

We believe that this Special Issue will provide a comprehensive platform for researchers, scientists, and healthcare professionals to exchange ideas, share their latest findings, and contribute to the advancement of magnetic and optical sensors for healthcare, medical, and bioscience applications. We look forward to your valuable contributions.

The alarming rise in chronic diseases worldwide highlights the urgent need to overcome the limitations of conventional drug delivery systems. In this context, osmotic pumps are able to release drugs by differential osmotic pressure, achieving a controlled rate independent of physiological factors and reducing the dosing frequency. As osmotic pumps are based on the phenomenon of osmosis, the choice of high osmolality draw solutions (DSs) is a critical factor in the successful delivery of the _target drug. Therefore, one alternative that has received particular attention is the formulation of DSs with magnetic nanoparticles (MNPs) due to their easy recovery, negligible reverse solute flux (RSF), and their possible tailor-made functionalization to generate high osmotic gradients. In this work, the possible integration of DSs formulated with MNPs in controlled drug delivery systems is discussed for the first time. In particular, the main potential advantages that these novel medical devices could offer, including improved scalability, regeneration, reliability, and enhanced drug delivery performance, are provided and discussed. Thus, the results of this review may demonstrate the potential of MNPs as osmotic agents, which could be useful for advancing the design of osmotic pump-based drug delivery systems. Full article

Optical and magnetic sensing methods are integral to both research and clinical applications in biological laboratories. The ongoing miniaturization of these sensors has paved the way for the development of point-of-care (PoC) diagnostics and handheld sensing devices, which are crucial for timely and efficient healthcare delivery. Among the various competing sensing and circuit technologies, CMOS (complementary metal–oxide–semiconductor) stands out due to its distinct cost-effectiveness, scalability, and high precision. By leveraging the inherent advantages of CMOS technology, recent developments in optical and magnetic biosensors have significantly advanced their application in life sciences, offering improved sensitivity, integration capabilities, and reduced power consumption. This paper provides a comprehensive review of recent advancements, focusing on innovations in CMOS-based optical and magnetic sensors and their transformative impact on biomedical research and diagnostics.
