A biomarker is a molecule that can be measured in a biological sample in an objective,
systematic, and precise way, whose levels indicate whether a process is normal or …

The detection and/or quantification of biomarkers in blood is important for the early
detection, diagnosis, and treatment of a variety of diseases and medical conditions. Among …

Interstitial fluid (ISF) contains a wealth of biomolecules, yet it is underutilized for diagnostic
testing due to a lack of rapid and simple techniques for collecting abundant amounts of fluid …

As point‐of‐care testing (POCT) is becoming the new paradigm of medical diagnostics,
there is a growing need to develop reliable POCT devices that can be conveniently operated …

Vitamin C (l-ascorbate) deficiency is a global public health issue most prevalent in resource-
limited regions, creating a need for an inexpensive detection platform. Here, we describe …

Currently, urine samples for bacterial or fungal infections require a long diagnostic period
(48 h). In the present work, a point-of-care device known as an electronic nose (eNose) has …

The emerging and exciting field of on-body wearable chemical sensing represents a major
transition away from common centralized laboratory-based analytical systems involving in …

Nanomaterials are widely used in immunochromatography due to their excellent physical
and chemical properties. However, traditional single-functional nanomaterials can only …

Polysaccharide-based materials are increasingly used for the development of point-of-care
(POC) devices or some of their components. This chapter aims to provide an overview of …
