How can nanotechnology be used to diagnose cancer?
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.
What are the most useful diagnostic technologies for cancer?
Imaging tests used in diagnosing cancer may include a computerized tomography (CT) scan, bone scan, magnetic resonance imaging (MRI), positron emission tomography (PET) scan, ultrasound and X-ray, among others.
Can nanoparticles detect cancer?
Nanotechnology has been applied in the development of nanomaterials3, such as gold nanoparticles and quantum dots, which are used for cancer diagnosis at the molecular level. Molecular diagnostics based on nanotechnology, such as the development of biomarkers, can accurately and quickly detect the cancers4.
How do nanoparticles work in cancer treatment?
Specially designed nanoparticles deliver medicines like chemotherapy straight to the tumor. They don’t release the medicine until they reach it. This stops the drugs from damaging healthy tissues around the tumor. That damage is what causes side effects.
What is the promise of nanotechnology for cancer detection and therapy?
Molecular diagnostics based on nanotechnology, such as the development of biomarkers, can accurately and quickly detect the cancers[4]. Nanotechnology treatments, such as the development of nanoscale drug delivery, can ensure precise cancerous tissue targeting with minimal side effects[5, 6].
What tests are run for cancer?
Diagnostic procedures for cancer may include imaging, laboratory tests (including tests for tumor markers), tumor biopsy, endoscopic examination, surgery, or genetic testing….What are the different types of lab tests used to diagnose cancer?
- Blood tests.
- Complete blood count (CBC)
- Urinalysis.
- Tumor markers.
How does a pathologist make a diagnosis?
The pathologist views the slides with the sections of the specimen under a microscope. Then, the pathologist creates a pathology report based on what is seen under the microscope. The report is very technical, using terms that are meaningful to other pathologists and doctors.
How do nanoparticles treat cancer?
How nanoparticles interact with cancer cells?
Once nanoparticles are endocytosed into cancer cells or phagocytic cells, they can release their cargo to exert a therapeutic effect. However, the strength of this effect depends not only on the rate of endocytosis but also on the accumulation and residence time of the nanoparticles inside cells.
What are the various materials used in diagnostics and therapeutic applications?
Commonly used nanomaterials for photo-triggered medical applications
- Gold-based NPs. The chief material that has been used for photothermal therapy (PTT) is gold and/or gold based materials.
- Carbon nanotubes.
- Inorganic photosensitizers.
- Polymeric nanocarriers for photosensitizer/dye encapsulation.
