Here are some ways nanomaterials are used in cancer treatment: [1] Nano-materials Aerosol Drug delivery systems: Nanoparticles can be loaded with anticancer drugs, improving drug solubility, stability, and targeted delivery to cancer cells. This enhances the drug's therapeutic effect while reducing side effects on healthy tissues. [2]
It can be directed to the location of cancer cells with sustained release behavior. Studies have also been done on gold nanoparticle responses to local near-infrared (NIR) light as a stimuli for drug release. In one study, gold nanoparticles functionalized with double-stranded DNA encapsulated with drug molecules, were irradiated with NIR light.
The overall drug consumption and side-effects may be lowered significantly by depositing the active pharmaceutical agent in the diseased region only and in no higher dose than needed. Targeted drug delivery is intended to reduce the side effects of drugs in tandem decreases in consumption and treatment expenses.
As a result, targeting the acidic microenvironment of tumors has emerged as a promising strategy for cancer therapy. One approach involves the use of creating drug delivery carriers that are sensitive to pH levels and have triggered drug release at the tumor site, thereby enhancing the efficacy of chemotherapy and other treatments.

Targeted delivery is believed to improve efficacy while reducing side-effects. When implementing a targeted release system, the following design criteria for the system must be taken into account: the drug properties, side-effects of the drugs, the route taken for the delivery of the drug, the targeted site, and the disease.
The uptake of thiolated gold nanoparticles has recently been monitored using 111In-labeled polymer shells that surround the gold nanoparticle and shows a possible way around this problem, but these polymer shells can be removed from the particle making a more stable labeling system required for these kinds of studies.
Experts say vehicle-based attacks are simple for a 'lone wolf' terrorist to plan and execute, and challenging for authorities to prevent.
Nanotubes can help with cancer treatment. They have been shown to be effective tumor killers in those with kidney or breast cancer. [4] [5] Multi-walled nanotubes are injected into a tumor and treated with a special type of laser that generates near-infrared radiation for around half a minute. These nanotubes vibrate in response to the laser ...
