low-concentration molecular biomarkers requires sending samples to centralized labs, leading to high costs and delays (Fig. 20.3.1). Recent developments in molecular diagnostics thus aim to enable point-of-care (POC) detection directly at or near the patient’s location [1–2]. The most successful POC technology to date is the paper-based lateral-flow assay (LFA) [3–4]. Examples include pregnancy tests that sense progesterone and SARS-CoV-2 rapid antigen tests. However, paper-based assays generally provide binary results or limited quantitative accuracy. On the other hand, the miniaturization of instrumentation, such as Abbott i-Stat Alinity, has enabled accurate diagnostics in hospital settings [5–6]. However, these devices remain costly and
