Applications of metal–organic framework-based bioelectrodes

Abstract

Metal–organic frameworks based bioelectrodes.

Advancing healthcare applications: wearable sensors utilizing metal–organic frameworks

“…Moreover, MOFs can be engineered to be highly selective, accurately distinguishing between similar biomolecules and reducing the likelihood of false-positive results. [196][197][198][199][200]…”

Enzymatic Electrochemical/Fluorescent Nanobiosensor for Detection of Small Chemicals

“…Among the several nanomaterials, the metal–organic framework (MOF) has attracted considerable attention from researchers in the biosensor field [ 93 , 94 ]. The MOF has unique properties and advantages in biosensing compared with other nanomaterials, such as (i) enabling target binding with probe molecules via π-π stacking [ 95 ], (ii) high surface area with porosity [ 96 ], (iii) easy functionalization and tailoring by controlling the ratio of metal ions in the MOF [ 97 ], and (iv) stability [ 98 ]. For example, organophosphorus pesticides (OPs), which can bind with AChe resulting in the breakdown of neurotransmitters, were detected using a MOF-applied nanobiosensor [ 99 ] ( Figure 5 B).…”

Ultrasensitive electrochemical detection of uric acid based on cobalt-embedded nitrogen-doped carbon

“…[20][21][22] Thanks to their multiple morphology/structure tunability and uniform heteroatom distribution, MOFs have proven to be ideal precursors for the construction of various carbonbased nanomaterials by pyrolysis under specific atmospheres (argon). [23][24][25][26] These MOF-derived porous carbon materials maintain the morphologically well-defined nanostructures of the precursors and offer many advantages such as being inexpensive, high specific surface area, good physicochemical stability, and easy functionalization by other heteroatoms, providing more active sites and higher charge transfer rates. The prior addition of metal ions to the MOF and subsequent growth pyrolysis to obtain atomically dispersed nanomaterials has also been demonstrated in some recent works.…”
