Azide Reactive LiposomesOnline Inquiry
Azide reactive liposomes are functional liposomes with azide reactive group modifications on the surface that can be conjugated to other chemical entities via click reactions. BOC Sciences is committed to providing you with high quality and competitively priced azide-reactive liposomes designed to use the process of click chemistry to concatenate antibodies to obtain immunoliposomes, advancing drug delivery and development in related fields.
What are Azide Reactive Liposomes?
Azide-reactive liposomes with azide (N3) groups on the surface can react with other molecules or compounds having complementary reactive groups, such as alkyne groups (-C=CH), to form covalent bonds via copper-free click chemistry. This reactivity allows for the attachment of various biomolecules, drugs or targeting ligands (especially antibodies) to the surface of liposomes for specific applications in drug delivery, diagnostics and therapy.

- Azide Functional Groups
Azido groups (-N3) are chemically reactive and can participate in a variety of bioconjugation reactions with high specificity, efficiency and biocompatibility. They are commonly used to link liposomes to other molecules or ligands such as antibodies, peptides, or visualizers. This is a stable and conjugated chemical structure that can play an important role in many biological applications such as biomarkers and drug delivery. Common groups that can click chemically with azide groups are in the following.
Alkyne Group, -C≡C-: The "Azide-Alkyne" click chemistry reaction is one of the most common and widely used click chemistry reactions, where the product formed is a stabilized triazole.
Cyclooctyne Group: The "Azide-Cyclooctyne" click chemistry, which has a lower background reaction relative to the alkyne moiety, can be used for highly selective conjugation in biology.
- Copper-free Click Chemistry
Copper-free click chemistry conjugation is a method used to attach material macromolecules to a carrier surface without the use of copper ions as a catalyst. The advantage of this method is not only that it can be performed in a biological environment, avoiding the toxicity of copper ions to biomolecules, but also that it is highly specific and efficient.

Applications of Azide Reactive Liposomes
Azide reactive liposomes are capable of promoting bioconjugation through click chemistry in downstream reactions and have a wide range of applications mainly in drug delivery system research, bioimaging, and targeted drug development.
- Drug Delivery System Development
Azide-reactive liposomes can be designed to load nucleic acid drugs, anticancer drugs, enzymes for the development of drug delivery systems.
- Targeted Drug Delivery
Azide-reactive liposomes can be functionalized with targeting ligands (e.g., antibodies or peptides) that specifically recognize a particular cell. This allows the corresponding drug to be selectively delivered to a specific site, reducing systemic side effects.
- Bioimaging Tools
Azide-reactive liposomes can be loaded with contrast agents or imaging probes with targeted molecular functionality. This enables specific imaging of diseased tissues or cells in vivo, contributing to early disease detection and monitoring of treatment response.
- Allowing Design of Multifunctional Modifications
Azide functionalization can be used to design liposomes with stimulus-responsive properties, such as pH-responsive or temperature-sensitive, to enable controlled and triggered drug release at specific sites.
