Abstract: Diabetes is a major public health burden whose prevalence has been steadily increasing
over the past decades. Glycated hemoglobin (HbA1c) is currently the gold standard for diagnostics
and monitoring of glycemic control in diabetes patients. HbA1c biosensors are often considered to
be cost-effective alternatives for smaller testing laboratories or clinics unable to access other reference
methods. Many of these sensors deploy nanomaterials as recognition elements, detection labels,
and/or transducers for achieving sensitive and selective detection of HbA1c. Nanomaterials
have emerged as important sensor components due to their excellent optical and electrical properties,
tunable morphologies, and easy integration into multiple sensing platforms. In this review, we
discuss the advantages of using nanomaterials to construct HbA1c sensors and various sensing
strategies for HbA1c measurements. Key gaps between the current technologies with what is needed
moving forward are also summarized.
