Nanomaterials including carbon nanotubes, polymeric micelles and liposomes have been used in cancer drug design where they have shown considerable pharmacokinetic and pharmacodynamic benefits in cancer diagnosis and treatment. In this review, we outline the commonly used nanomaterials which are employed in cancer diagnosis and therapy.
What kind of cancer can be treated with nanotechnology?
Doxil treats ovarian cancers, multiple myeloma, and Kaposi's sarcoma. Researchers are studying other nanotechnology treatments in clinical trials. Some of these treatments wrap toxic drugs in nanoparticles to make them safer, or to help the drug survive the trip through the bloodstream.
What are the commonly used nanomaterials in cancer drug design?

In this review, we outline the commonly used nanomaterials which are employed in cancer diagnosis and therapy.
What are nanocarriers used for in cancer treatment?
These therapeutics are used in many cases to target ‘undruggable’ cancer proteins. Additionally, the increased stability of genetic therapies delivered by nanocarriers, and often combined with controlled release, has been shown to prolong their effects.
Do nanoparticles serve as carriers for drug delivery in cancer?
Nanoparticles as carriers for drug delivery in cancer. Artif Cells Nanomed Biotechnol. 2018;46(sup2):295–305. doi: 10.1080/21691401.2018.1457039. [PubMed] [CrossRef] [Google Scholar]
What types of nanoparticles are used in cancer treatment?
Different types of nanoparticles (NPs) for cancer therapy. NPs applied to drug delivery systems include organic NPs, inorganic NPs and hybrid NPs. The organic NPs contain liposome-based NPs, polymer-based NPs and dendrimers. Among polymer-based NPs, polymeric NPs and polymeric micelles are common.
How is nanotechnology being used in cancer treatment?
Nanotechnology can provide rapid and sensitive detection of cancer-related molecules, enabling scientists to detect molecular changes even when they occur only in a small percentage of cells. Nanotechnology also has the potential to generate entirely novel and highly effective therapeutic agents.
How are nanotubes used for cancer?
Through appropriate functionalization, CNTs have been used as nanocarriers to transport anticancer drugs, genes, and proteins for chemotherapy. They have also been used as mediators for photothermal therapy (PTT) and photodynamic therapy (PDT) to directly destroy cancer cells.
Are nanoparticles being used in cancer treatment?
Nanoparticles are a promising treatment option for cancers that are resistant to common therapies. In a new study that demonstrates an innovative and non-invasive approach to cancer treatment, Northwestern Medicine scientists successfully used magnetic nanoparticles to damage tumor cells in animal models.
Which delivery system is first approved nanoparticles for cancer?
Abraxane® or nab-paclitaxel is the first clinically approved nanostructured polymer–drug conjugate (36). Compared to conventional paclitaxel administration, albumin-based nanoparticles demonstrated enhanced biocompatibility and tumor accumulation of paclitaxel (38).
How are nanoparticles used in cancer diagnosis and treatment?
Nanoparticles can selectively target cancer biomarkers and cancer cells, allowing more sensitive diagnosis; early detection requiring minimal amount of tissue, monitoring of the progress of therapy and tumor burden over time, and destruction of solely the cancer cells.
How are carbon nanotubes used in cancer treatment?
Carbon nanotubes (CNTs), due to their unique physicochemical properties, have become a popular tool in cancer diagnosis and therapy. They are considered one of the most promising nanomaterials with the capability of both detecting the cancerous cells and delivering drugs or small therapeutic molecules to these cells.
How do carbon nanotubes deliver anticancer drugs to the site of a tumor?
Drugs can either attach to the outer surface of the CNT via functional groups or be loaded inside the CNT. Attachment of the anticancer drug to the outer surface of the CNT can be through either covalent or noncovalent bonding, including hydrophobic, π–π stacking, and electrostatic interactions.
How do nanotubes deliver drugs?
Shorter carbon nanotubes are absorbed into the body more easily through oral routes, passing through columnar cells of the intestines. Carbon nanotubes delivered subcutaneously tend to linger in the area of injection, before slowly diffusing away from the region and passing through the lymph system.
What are the types of nanoparticles?
Nanoparticles can be classified into different types according to the size, morphology, physical and chemical properties. Some of them are carbon-based nanoparticles, ceramic nanoparticles, metal nanoparticles, semiconductor nanoparticles, polymeric nanoparticles and lipid-based nanoparticles.
Why are nanoparticles used in chemotherapy?
The technique involves storing a cancer drug inside tiny objects called nanoparticles. Using this method, researchers were able to shrink tumors in mice while using smaller doses of the drug to reduce harmful side effects. The chemotherapy drug cisplatin is an effective cell killer.
What nanoparticles are used in medicine?
DOX and magnetic nanoparticles were incorporated into PLGA nanoparticles, with DOX serving as an anticancer drug and Fe2O3 nanoparticles used as an imaging agent (Figure 1). They also used antibody herceptin 1 for targeting the breast cancer.
