Nonetheless, although GMABs stand out significantly from traditional alternatives, there is still no consensus on their behavior regarding chemical, rheological, microstructural, morphological, thermogravimetric, and surface topography properties. In the literature, it has been reported that (in comparison to an unmodified binder) the Graphene Modified Asphalt Binders (GMABs) exhibit an enhanced performance grade, a lower thermal susceptibility, a higher fatigue life, and a decreased accumulation of permanent deformations. For instance, graphene-like materials have been employed as asphalt binder modifying agents in pavement engineering. Graphene is a carbon-based nanomaterial used in various industries to improve the performance of hundreds of materials. Additionally, the constraints and difficulties with specimen and analysis that are related to comprehending nanostructured materials have been identified and addressed in this study. The essence of the nanomaterials as they relate to physics, chemistry, and biology is thoroughly explained in this overview along with characterization techniques through case In addition, composition analysis techniques such as X-ray Photoelectron Spectroscopy (XPS), Energy Dispersive X-ray spectroscopy (EDS), Auger Electron Spectroscopy (AES), and Secondary Ion Mass Spectroscopy (SIMS) have been discussed. In addition, the internal structural investigation techniques X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), and Magnetic Resonance Force Microscopy (MRFM) are discussed. Near-field Scanning Optical Microscopy (NSOM), and Confocal microscopy, are described. In this article, the techniques for analysing the topology of nanostructures, including Field Emission Scanning Electron Microscopy (FESEM), Dynamic Light Scattering (DLS), Scanning Probe Microscopy (SPM), This overview article illustrates the present state of nanostructured materials in the biomedical field with uses and the importance of characterisation methods through the use of cutting-edge characterisation techniques. We may therefore investigate the nanostructured materials for biomedical applications with the aid of modernĬharacterization techniques. Biological activity, compatibility, toxicity, and nano-bio interfacial characteristics are some of the major problems in biomedicine. Before using nanostructured materials in clinical applications, many important challenges, especially those related to their uses in biomedicine, must be resolved. Recent advancements in nanostructured materials have found widespread application across many domains, particularly in the biomedical field. Finally, the future outlook has been drawn to address the obstacles and encourage further studies in this vital discipline. This review article can assist students, physicists, and chemists choose the best characterization technique for investigating the fabricated semiconductor heterojunction and possibly other relevant materials. Furthermore, the practical applications of photocatalytic degradation using semiconductor heterojunctions were concisely reviewed using recently reported examples. Therefore, the main aims of this review are to discuss the most critical characteristics of semiconductor photocatalysts by summarizing the main characterization techniques, including the structure and chemical composition (XRD, FTIR, XPS, EDX, and Raman spectra), morphological properties (SEM, TEM, HRTEM, and BET), and optical and photoelectrochemical properties (DRS, EIS, PL, and the transient photocurrent responses). However, there are a lot of reviews and research articles concentrating on the fabrication of varying semiconductor heterojunctions for environmental purification, but only a few published reviews discussed and summarized the comprehensive characterization techniques for such heterojunctions. The creation of numerous semiconductor heterojunctions exhibited long-standing popularity in the field of the photocatalysis process due to its great potential for the degradation of different organic pollutants, stimulating the development of numerous characterization techniques. In the past decade, the release of various organic pollutants from industries and anthropogenic activities has jeopardized natural resources.
