Nanotechnology has a vital role in the healthcare sector – to develop novel drug carriers and specific at-targeted delivery towards tumors. Nanomedicines are carried by small devices at a range of 1-100 nm. Such small devices can be highly beneficial for the clinical practice of medicines. Nanomedicine is an application of nanotechnology with maximum possibilities to cure a disease. It works at a molecular level. It helps to diagnose in-depth damaged tissues, treat or prevent diseases, and improve human health.
Nanotechnology increases some basic properties like efficacy, solubility, and immunogenicity, maximizes the product lifecycle and bioavailability and reduces toxicity. Its main focus is on cancer cure, Alzheimer’s, lung diseases, and neurological disorders.
Nanotechnology has some major applications in:
– Cell repair
– Diagnostic techniques
– Drug delivery
Nanotechnology has a broad spectrum of applications at the therapy level in cancer treatment as well as for lung diseases, Alzheimer’s, and neurological disorders. Nanotechnology is therapeutic at the molecule level, improves the effectiveness of treatments, and reduces toxicity with minute damage to living cells. Nanotechnology has incredible property to carry immunomodulatory molecules with radiotherapy or chemotherapy. It reduces the time and cost of therapy.
Nanostructures are now being involved in the regenerative medicine creation of biomaterials and clinical implications while Nanorobots are being used to repair damaged tissues. Nanoshells are linked to antibodies and recognize the tumor cells by applying infrared light. They create intense heat and kill the cancer cells with less affecting the healthy cells.
There are some diseases threatening humans that cannot be diagnosed at the atomic level. Nano devices can diagnose various diseases like cancer, diabetes, brain diseases, cardiac diseases, etc. at more intricate levels.
Nowadays, there are new methodologies to diagnose a disease easily. A patient can use these devices themselves. For example, diabetic patients have to take blood samples many times in a day to control glucose levels and they are uncomfortable with such procedures. But, innovative devices like nanorobotics can solve such problems by monitoring glucose levels. Nanorobotics can record patient information for further treatment and diagnosis by doctors or specialists. The historical data can be crucial in changing a patient’s life.
The traditional modes of drug delivery sometimes eliminate living cells also in the human body. Nanotechnology introduces modern methods for drug delivery to specifically target and terminate foreign bodies and reduce toxicity. It can deliver to tiny areas within the body.
