A single-domain antibody is called a "nanobody." Single-domain antibodies have one monomeric variable antibody domain and can bind specifically to a specific antigen. They are very useful in the treatment of various immune system disorders. Nanobodies are single-domain antibodies derived from llamas. Their robust structure and small size make them ideal for drug development and research. They are highly specific and have a high affinity for a single target. Their specificity and low immunogenicity make them a promising tool for drug discovery. However, nanobodies have lower levels of immunogenicity compared to mAbs, making them more difficult to produce and store.

In July 2021, the Max Planck Institute, a non-profit research firm in Germany, partnered with the University Medical Center Goettingen to develop highly potent nanobodies to block the SARS CoV-2 virus. Nanobodies have the potential to be useful drugs for the treatment of many diseases. Scientists at the University of Liverpool and the University of Oxford have produced a chain of three nanobody molecules that neutralized the original variants of SARS-CoV-2, the Beta and Alpha, in hamsters.

The advantages of nanobodies over human antibodies are varied. These drugs are less expensive to produce and can be delivered directly to the infection site. They can also be administered at home without the need for an injection. And they don't require a patient to undergo a painful procedure or wait for a lengthy treatment. Since they are easier to manufacture, they are also more convenient for consumers, as they don't need to undergo a complicated process.

Since nanobodies are single-domain antibodies, they have high stability and solubility. In addition, nanobodies are useful as biosensors since they can target microbes, viruses, and cancer. They're also highly effective for modifying the immune system. As a result, they are useful in clinical trials.

Nanobodies are often used to treat infections. They can be used as a substitute for anti-virals and other treatments. Since they are so small, they can be more effective than traditional anti-virals. The first phase is to optimize them for pulmonary delivery. Then, the next step is to test the antibodies for efficacy. These antibodies may be beneficial in treating several types of viral infections. They may also be helpful in preventing cancer.
