Special Issue Information

Dear Colleagues,

Biosensors are analytical tools that facilitate the accurate diagnosis and analysis of biological states and diseases in living systems. These diagnostic devices detect and quantitatively measure biological and pathological analytes in order to aid a better understanding of the biological processes and changes in cells and tissues. Much innovative research is being carried out to create high-accuracy and cost-effective optical biosensors that can help with disease diagnoses. New advancements, especially in the field of optical methods for biosensing, are essential as these biological detection and imaging tools find a wide range of potential applications in healthcare, medicine, and more.

In this Special Issue of Biosensors, we invite you to contribute high-quality research on Advanced Optical Methods for Biosensing and Bioimaging. Contributions that cover both experimental and theoretical work on the latest developments in the field of optical biosensors will be considered. Original research papers, communication, research notes, and comprehensive review articles are welcome. Manuscripts will be internationally peer-reviewed.

Noninvasive in situ monitoring of viscoelastic characteristics of corneal tissue at elevated temperatures is pivotal for mechanical property-informed refractive surgery techniques, including thermokeratoplasty and photorefractive keratectomy, requiring precise thermal modifications of the corneal structure during these surgical procedures. This study harnesses Brillouin light scattering spectroscopy as a biosensing platform to noninvasively probe the viscoelastic properties of ovine corneas across a temperature range of 25–64 °C. By submerging the tissue samples in silicone oil, consistent hydration and immiscibility are maintained, allowing for their accurate sensing of temperature-dependent mechanical behaviors. We identify significant phase transitions in the corneal tissue, particularly beyond 40 °C, likely due to collagen unfolding, marking the beginning of thermal destabilization. A subsequent transition, observed beyond 60 °C, correlates with collagen denaturation. These phase transformations highlight the cornea’s sensitivity to both physiologically reversible and irreversible viscoelastic changes induced by mild to high temperatures. Our findings underscore the potential of the Brillouin biosensing technique for real-time diagnostics of corneal biomechanics during refractive surgeries to attain optimized therapeutic outcomes.
