Holographic sensors: Three-dimensional analyte-sensitive nanostructures and their applications

A study is conducted to establish a theoretical framework for holographic sensing, define terminology in holographic sensing, demonstrate how holographic sensing fits into the existing body of sensing mechanisms, and highlight gaps in the previous research. The study aims at integrating and summarizing what is known in holographic sensing, identifying where the major questions remain, and enabling others in the field to be able to replicate the existing experimental setups for fabricating and interrogating holographic sensors. It scope consists of the latest techniques for producing holographic sensors, and their potential applications in research, industrial settings, and among the public. The study also discusses the need for optical sensing, the fundamentals of holography, the origins of holographic sensors, holographic media and materials, fabrication techniques, sensing capabilities, readouts, and relevant theoretical studies.
