Antibody affinity is a core metric in immunology and biopharmaceutical science. It refers to the strength of the interaction between a single antigen epitope and the paratope (binding site) of an antibody. In the case of VHH antibodies, also called single-domain antibodies or nanobodies, this interaction occurs through the unique, compact paratope located on their heavy-chain-only variable domain.

VHH antibodies are single-domain antibody fragments derived from the unique heavy-chain-only antibodies (HCAbs) of camelids, including alpacas, llamas, and camels.

Antibody thermal stability refers to the ability of an antibody to retain its structural conformation and binding function when exposed to elevated temperatures. It includes both chemical and physical aspects of protein integrity. Thermal stability is especially critical in therapeutic and diagnostic applications where antibodies must remain effective during manufacturing, shipping, storage, and use.

Antibody fragments have become indispensable in modern biotechnology due to their smaller size, improved tissue penetration, and suitability for engineered constructs. Among these, camelid VHH nanobodies (single-domain antibodies) and single-chain variable fragments (scFvs) represent two widely studied and applied formats. Both can be produced recombinantly and tailored for diagnostic or therapeutic use, yet their origins, molecular structures, and functional properties are distinct.
