Liquid biopsy is a minimally invasive method that involves the analysis of circulating tumor cells and other biomarkers in bodily fluids. This non-invasive approach has revolutionized cancer diagnostics and monitoring by enabling real-time assessment of tumor dynamics and treatment response. For example, liquid biopsy has been utilized to detect actionable mutations in cancer patients, guide treatment decisions, and monitor the emergence of treatment resistance (Vatandoost et al., 2019). The use of liquid biopsy in early cancer detection and surveillance holds great promise for enhancing patient results through timely interventions and personalized treatment strategies. Furthermore, liquid biopsy offers a non-invasive method for monitoring disease recurrence and response to therapy, reducing the need for repeated tissue biopsies and providing a more comprehensive assessment of tumor heterogeneity.
4.2.3 High-throughput screening
High-throughput screening (HTS) platforms have revolutionized drug discovery and development by enabling the rapid testing of thousands to millions of compounds for their biological activity (Andreu-Perez et al., 2015). By automating the screening process and incorporating advanced data analysis techniques, HTS has accelerated the identification of novel drug candidates and the repurposing of existing drugs for new indications. For instance, HTS has been instrumental in identifying small molecule inhibitors of diseasespecific targets, leading to the development of targeted therapies for a multiplicity of illnesses, including autoimmune disorders and infectious diseases. The integration of HTS with computational modeling and artificial intelligence has further enhanced the efficiency and reliability of drug discovery, allowing more precise and effective therapeutics (Kim 2019).
4.2.4 Point-of-care testing
Point-of-care testing (POCT) has transformed healthcare delivery by bringing diagnostic testing closer to the patient, enabling rapid and on-the-spot analysis of various biomarkers and analytes. POCT devices are compact, portable, and user-friendly, allowing for quick and accurate diagnosis of diseases such as infectious diseases, diabetes, cardiovascular conditions, and more. By reducing the turnaround time for test results and enabling immediate treatment decisions, POCT has improved patient outcomes, particularly in emergency and critical care settings (Bennett, 2014). For example, POCT devices for measuring blood glucose levels have transformed the management of diabetes by enabling patients to monitor their blood sugar levels at home and adjust their treatment regimen accordingly. The widespread adoption of POCT has also reduced healthcare costs by minimizing the need for unnecessary hospital visits and expedited treatment initiation.
