Paper-based analytical devices (PADs) enable the affordable, easy, rapid, and reliable detection of a range analytes at point-of-care. Cellulose is versatile substrate for antibody attachment. However, how immunoreagents are immobilized onto cellulose plays an important role in assay performance. To provide overview different immobilization strategies used developing PADs, we here critically review existing literature from last decade (2013-2023). First, introduce as summarize fabrication techniques PADs. Thereafter, delve into antibodies passively, covalently, or by affinity linkage. Affinity-based further explored case study focused on using recombinant bifunctional proteins with cellulose-binding modules to anchor cellulose. The final section discusses validation sustainable development PADs addressing future challenges associated such devices.
