A team of researchers from the Universidad del País Vasco uses nanohydrogels to release drugs in a controlled manner. These hydrogels are capable of detecting changes in the PH that in area where cancer is localized drops to values between 4.7 and 5.2, being the normal value of 7.4. The investigators used folic acid to functionalize these nanohydrogels in order to act as a ‘Trojan horse’, since that folic acid has the ability to detect cancer cells and misleading.

Thanks to nanohydrogels drugs could be released in cancer cells without affect healthy cells.

The group that has developed these nanohydrogels is also studying their application with tuberculosis drugs.
