Description
Summary:Photonic crystal (PC)-based inverse opal (IO) arrays are one of the substrates for label-free sensing mechanism. IO-based materials with their advanced and ordered three-dimensional microporous structures have recently found attractive optical sensor and biological applications in the detection of biomolecules like proteins, DNA, viruses, etc. The unique optical and structural properties of IO materials can simplify the improvements in non-destructive optical study capabilities for point of care testing (POCT) used within a wide variety of biosensor research. In this review, which is an interdisciplinary investigation among nanotechnology, biology, chemistry and medical sciences, the recent fabrication methodologies and the main challenges regarding the application of (inverse opals) IOs in terms of their bio-sensing capability are summarized. [Display omitted] •The recent main challenges regarding the application of inverse opals (IOs) in the detection of biomolecules are reviewed.•Sensing mechanisms of biomolecules including glucose, proteins, DNA, viruses were summarized.•IO materials with their ordered 3D microporous structures have found attractive optical biosensor applications.
