Diabetes mellitus is a prevalent chronic health condition
that
has caused millions of deaths worldwide. Monitoring blood glucose
levels is crucial in diabetes management, aiding in clinical decision
making and reducing the incidence of hypoglycemic episodes, thereby
decreasing morbidity and mortality rates. Despite advancements in
glucose monitoring (GM), the development of noninvasive, rapid, accurate,
sensitive, selective, and stable systems for continuous monitoring
remains a challenge. Addressing these challenges is critical to improving
the clinical utility of GM technologies in diabetes management. In
this concept, cyclodextrins (CDs) can be instrumental in the development
of GM systems due to their high supramolecular recognition capabilities
based on the host–guest interaction. The introduction of CDs
into GM systems not only impacts the sensitivity, selectivity, and
detection limit of the monitoring process but also improves biocompatibility
and stability. These findings motivated the current review to provide
a comprehensive summary of CD-based blood glucose sensors and their
chemistry of glucose detection, efficiency, and accuracy. We categorize
CD-based sensors into four groups based on their modification strategies,
including CD-modified boronic acid, CD-modified mediators, CD-modified
nanoparticles, and CD-modified functionalized polymers. These findings
shed light on the potential of CD-based sensors as a promising tool
for continuous GM in diabetes mellitus management.
