This challenge is particularly pronounced when dealing with trace amounts of isomers in biological samples, where matrix effects can further complicate separation and detection.

Another significant hurdle is the potential for isomerization during sample preparation and analysis. Geometric isomers can interconvert under certain conditions, such as exposure to heat, light, or pH changes. This instability poses a considerable challenge in maintaining the integrity of samples throughout the analytical process, from collection to final measurement. Researchers must develop and validate robust protocols that minimize isomerization risks, which often requires specialized handling and storage conditions.

The lack of standardized methodologies for geometric isomer analysis also presents a challenge. Different laboratories may employ varied approaches, leading to inconsistencies in results and difficulties in comparing data across studies. This absence of harmonized protocols hampers the establishment of reliable reference ranges for isomeric biomarkers and impedes the translation of research findings into clinical applications.

Furthermore, the development of sensitive and specific detection methods for geometric isomers remains an ongoing challenge. While mass spectrometry has emerged as a powerful tool, the differentiation of isomers with identical molecular masses requires advanced techniques such as ion mobility spectrometry or specialized fragmentation methods. These sophisticated approaches often demand significant expertise and resources, limiting their widespread adoption in routine analyses.

The interpretation of geometric isomer data in the context of biomarker research also presents challenges. Establishing clear correlations between isomeric profiles and specific physiological or pathological states requires extensive validation studies and a deep understanding of the biological significance of isomeric variations. This process is further complicated by the potential influence of genetic factors, environmental exposures, and lifestyle variables on isomeric distributions in biological systems.

The research on geometric isomers as biomarkers in physicochemical analysis is in an emerging stage, with growing market potential due to its applications in pharmaceutical and biotechnology industries.
