Are nanotextures enough to kill cancer cells?

Nanotextures on nanoparticles and implants to kill cancer cells in a more targeted manner may just be the key to tackling resistance to traditional cancer drugs. Is our fight against cancer complete? Consider that although for many cancer diagnoses, while people are living longer, the rate of cancer metastasis is still increasing.(1) Further, consider that prostate and some other select cancers remain persistent with only a few new approaches, and even those are not working.(2) In fact, most oncologists only look to the drug industry (a.k.a., Big PHARMA) to develop new drugs to help them. Does anyone believe this is the best we can do? Are chemotherapeutics really the answer? Have drugs worked for eradicating infection (e.g. antibiotic-resistant bacteria) or for treating chronic pain (e.g. opioid addiction)?
