01 How Nanobodies Work
02 Importance & Emergence
03 Current & Future Applications
04 Key Challenges to Navigate
05 The Nanobody Decade: What's Next
06 Conclusion & Key References

Six chapters of technical depth

From camelid structural biology to preclinical immunoassay formats and research-grade binding reagents - grounded in peer-reviewed science throughout.

01
How Nanobodies Work
Structural origins from camelid HCAbs, CDR biology, phage display production, engineering formats (bivalent, Fc-fusion, PEGylated, radiolabelled), and exceptional biophysical properties.
Structural Biology
02
Importance & Emergence
Why conventional antibodies fall short, the 1989 discovery and 1993 Nature paper, Caplacizumab's FDA approval in 2019, and what foundational patent expiry means for reagent manufacturers and assay developers.
History & IP Landscape
03
Current & Future Applications
Lateral flow and immunoassay formats in a preclinical research context, sandwich ELISA development, research tools (GFP-Trap, intrabodies, chromobodies, cryo-EM chaperones), and preclinical assay platforms including HTRF and flow cytometry.
Immunoassay & Research Tools
04
Key Challenges to Navigate
Immunogenicity and humanisation, assay standardisation and lot qualification, GMP manufacturing at scale, and the evolving IP landscape as foundational patents expire.
Development Considerations
05
The Nanobody Decade
AI-driven discovery compressing lead identification from months to days, synthetic human VHH libraries, cell and gene therapy applications, and the democratisation of preclinical research tools.
Future Outlook
06
Conclusion & References
A framework for researchers and preclinical assay developers - with 12 peer-reviewed references spanning Nature, PNAS, Annual Review of Biochemistry, and EMA regulatory reports.

Written for the people doing the work

Research Scientists

Using nanobodies as research tools - GFP-Trap, intrabodies, chromobodies, cryo-EM chaperones, or proximity labelling systems.

Assay Developers

Building lateral flow, ELISA, HTRF, or multiplexed immunoassay platforms and evaluating nanobodies as a replacement for conventional antibody reagents.

Preclinical Assay Developers

Building and validating immunoassay platforms using nanobodies as research-grade capture and detection reagents, ahead of any downstream commercial or regulatory pathway.
