Porous inorganic materials play an important role in adsorbing targeted analytes and supporting efficient reactions in analytical science. The detection performance relies on the structural properties of porous materials, considering the tunable pore size, shape, connectivity, etc. Herein, we first clarify the enhancement mechanisms of porous materials for bioanalysis, concerning the detection sensitivity and selectivity. The diagnostic applications of porous material-assisted platforms by coupling with various analytical techniques, including electrochemical sensing, optical spectrometry, and mass spectrometry, etc., are then reviewed. We foresee that advanced porous materials will bring far-reaching implications in bioanalysis toward real-case applications, especially as diagnostic assays in clinical settings.

In recent years, graphitic carbon nitride (g-C 3 N 4) has attracted much attention due to its unique properties and excellent performance in the field of sensors, which has inspired the authors to compile this review. Although there are many reviews on the synthesis and applications of g-C 3 N 4 materials, a targeted, systematic, comprehensive summary of applications in sensors and the sensing mechanisms of g-C 3 N 4-based nanomaterials have not been published. In this review, the preparation methods and synthetic conditions for preparing g-C 3 N 4 with different morphologies, such as conventional bulk g-C 3 N 4 , g-C 3 N 4 nanosheets, and g-C 3 N 4 quantum dots, are introduced in detail. By reviewing recent advances in g-C 3 N 4-based nanomaterials in ion sensors, biosensors, gas sensors and humidity sensors, this study provides more comprehensive and in-depth information for the further design of g-C 3 N 4based sensors with enhanced performance. A brief outlook of g-C 3 N 4-based sensors is presented as the conclusion of this review.
