Abstract: Liquid crystals (LCs) have undergone a remarkable evolution, shifting from their initial role in flat-panel display technologies to becoming promising functional materials in biomedicine. Their unique physicochemical characteristics—including anisotropy, high sensitivity to external stimuli, and self-organizing behavior—make them highly suitable for the design of smart medical systems. In recent years, liquid crystals have been extensively explored in bio sensing, where their orientation changes enable label-free, real-time detection of biomolecules such as proteins, DNA, and toxins. They have also demonstrated potential in medical imaging, enhancing diagnostic precision through their optical and structural properties. Furthermore, liquid crystal phases serve as efficient platforms for drug delivery, offering improved stability, biocompatibility, and controlled release triggered by physiological conditions. This review highlights the transition of liquid crystals from display technology to advanced biomedical applications, emphasizing their role as a bridge between material science, physics, and modern medicine. Such developments position liquid crystals as key enablers of next-generation smart healthcare solutions.
