Recent advances in multi-omics approaches, including genomics, transcriptomics, proteomics, metabolomics, cytometry and imaging, in combination with bioinformatics and biostatistics, have been translated into several popular bioanalytical platforms, such as next-generation sequencing (NGS kits), single-cell analysis, flow cytometry and mass spectrometry. These platforms, although widely adopted, require tissue fixation and are therefore not capable of providing
