“…In preparation of IOPCs via the colloidal crystal template technique, generally, PS, PMMA or SiO 2 microspheres are orderly arranged into opal PC templates [ 47 ]. The PCs were prepared through gravity sedimentation or centrifugal sedimentation, self-assembly, evaporation, dip coating or electrophoresis methods [ [48] , [49] , [50] ]. Then various target materials or precursor is filled in the prepared opal PCs template using deposition or hydrolysis.…”

“…Biosensors mediated optical measurements have usually proven to be reliable, faster, compact, and user-friendly than those applying electrochemical and conventional optical bio-sensing systems [ 1 , 2 ]. Sensitive bio-sensing technologies such as surface plasmon resonance (SPR), electrochemical biosensors and recently inverse opal photonic crystals (IOPCs) biosensors, have been employed as diagnostic devices for the detection of biomarkers [ [3] , [4] , [5] , [6] , [7] , [8] ]. Photonic crystals (PCs) are dielectric and nanostructured materials with optical sensing properties and wide range applications in the field of optoelectronics and photonics [ [9] , [10] , [11] ].…”

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.

Optical sensors for biomedical applications have gained prominence in recent decades due to their compact size, high sensitivity, reliability, portability, and low cost. In this review, we summarized and discussed a few selected techniques and corresponding technological platforms enabling the manufacturing of optical biomedical sensors of different types. We discussed integrated optical biosensors, vertical grating couplers, plasmonic sensors, surface plasmon resonance optical fiber biosensors, and metasurface biosensors, Photonic crystal-based biosensors, thin metal films biosensors, and fiber Bragg grating biosensors as the most representative cases. All of these might enable the identification of symptoms of deadly illnesses in their early stages; thus, potentially saving a patient’s life. The aim of this paper was not to render a definitive judgment in favor of one sensor technology over another. We presented the pros and cons of all the major sensor systems enabling the readers to choose the solution tailored to their needs and demands.
