This study aimed to synthesize and test gelatin-functionalized graphene oxide (gelatin-GO) for simultaneous chemical and photothermal cancer therapy. The researchers synthesized gelatin-GO and tested its photothermal capabilities and ability to deliver drugs. They found that gelatin-GO heated up over 3 times more than water when exposed to laser light, showing promise for photothermal therapy. Drug release experiments also showed that chemicals loaded onto gelatin-GO were released over time, demonstrating its potential as a drug carrier. Future work will involve testing gelatin-GO's abilities to deliver actual cancer drugs and applying it to in vivo cancer treatment.
