What is dendrimers?

Dendrimers are used as well-defined scaffolding or nanocontainers to conjugate, complex or encapsulate therapeutic drugs or imaging moieties.

New cocktail?We know that the release of physically

entrapped guest-type drugs in dendrimeric hosts might be controlled by both surface modification and the density of modifying groups.

Well , what can we do?
