Nanobodies (Nbs)
the antigen-binding single-domain fragments derived from camelid heavy-chain antibodies (Abs)
have rapidly become a focus of biomedical research due to their compact size
high stability
strong antigen affinity
and ease of molecular engineering. This review systematically outlines their structural and functional features
current strategies for acquisition
screening
optimization
and large-scale production
and comprehensively discusses their wide-ranging applications in therapeutics
diagnostics
and basic research. Specifically
Nbs have shown outstanding efficacy in tumor
toxin
infectious
and cardiovascular disease treatments
while serving as versatile tools for molecular imaging
biosensing
protein purification
structural analysis
and intracellular regulation. The challenges of immunogenicity
off-target effects
and industrial-scale manufacturing are also critically examined. Furthermore
the integration of artificial intelligence in structure prediction
de novo design
and immunogenicity assessment has opened powerful new avenues for rational Nb engineering. Combined with emerging technologies such as gene therapy
nanomaterial delivery
and multispecific architectures
these advances promise to accelerate clinical translation. Overall
Nb technology is poised to become a cornerstone of next-generation precision medicine and biotechnology
offering innovative solutions for disease diagnosis
targeted therapy
and molecular discovery.
