Nanotechnology-based intelligent drug design for cancer Metastasis treatment

Nanotechnology is becoming an important tool in modern healthcare, especially for
improving drug delivery methods. Most chemotherapy treatments currently used for cancer
were developed decades ago during the early period of the cancer research movement. While
these drugs are effective at killing cancer cells in laboratory settings, they often have harmful
effects on healthy cells in the body. This intrinsic imprecision can engender considerable
detrimental consequences, including increased toxicity, impaired immune responses, and a
reduced quality of life for those impacted. To address these limitations, Nano medicine has
surfaced as an innovative approach to cancer treatment. Nanoparticles possess unique
physical and biological characteristics that enable the more accurate delivery of therapeutic
compounds to tumoursites. As a result, targeted drug delivery systems (TDDS) utilizing
nanotechnology can augment drug concentrations at the tumour , while simultaneously
lessening damage to healthy tissues . This article discusses various nanotechnology-based
pharmaceutical platforms used for cancer metastasis therapy, highlighting their design
strategies, benefits, and limitations compared with conventional chemotherapy. Additionally,
it evaluates how nanomaterials may enhance the effectiveness and safety of treatments aimed
at controlling and treating cancer metastasis.
