STRINGING drug molecules into fibres that unravel in the presence of a specific enzyme could allow medication to be released exactly when and where it is needed.
Previously, drugs have been bundled with polymers that, once injected into a patient, slowly break down to release the drug. By tuning the properties of the polymer, this allows the timing of a drug’s release to be pre-programmed. However, the polymers can release toxic molecules as they degrade.
Now George John from the City University of New York and team have created a way to pre-program drug release without using potentially harmful…
