14.1 Introduction

Metal-organic frameworks (MOFs) are a class of porous materials that are composed of

metal ions or clusters linked by organic ligands. These materials possess ultra-high porosity

combined with large internal surface areas of more than 6,000 m²/g. In addition to this, the

large degree of variability in terms of both organic and metal nodes provides huge potential

for applications in diverse fields [1]. Fields like adsorption of antibiotics, pollutants, bio­

molecules, gas adsorption, photo and electrocatalysis, biosensors, fuel cells, supercapacitors,

and batteries have all benefited from the application of MOFs. The MOF materials are made

using facile synthesis strategies like solvothermal methods, layer-by-layer growth, micro­

wave, electrochemical, mechanochemical, and high throughput methods [2]. The properties

of MOFs like porosity, flexibility in materials design, and availability of large surface areas

offer immense possibilities for various applications. The conductivity and functionality of

these materials can also be engineered using various strategies, which makes these materials

ideal candidates for wearable sensing and nanogenerator applications.

This chapter deals with the application of MOFs for bioelectronics applications.

Bioelectronics is the branch of science concerned with the use of electronic devices in

living systems. Specifically, the application of MOFs for wearable standalone
