Can nanotechnology potentiate photodynamic therapy?

Studies have demonstrated that nanoemulsions can enhance preferential delivery of PS to tumor sites and thus diminish the toxic side effects of PDT [41]. The application of nanoemulsions in PDT is likely to be in topical application of PS to the skin or to other mucosal surfaces.

What is Nano therapy?

Nanotherapy is the branch of nanotechnology dealing with the application of the nanoparticles for treating various ailments of humans and animals. Nanotechnology now makes it possible to precisely target human and animal diseases with minimal side effects.

Which laser is used in photodynamic therapy?

Photodynamic therapy utilizing Photofrin and 630 nm light delivered via fiberoptics attached to a 630-nm emitting laser, was the first drug/device approval for oncology issued by the FDA. Subsequent approvals have been obtained in PDT utilizing other photosensitizers and light emitting devices.

Is nanotechnology better than chemotherapy?

Nanotechnology targets cancer cells more exactly to spare healthy tissues. In theory, it should cause fewer side effects than current treatments like chemotherapy and radiation.

Can nanotechnology be harmful?

Nanoparticles are likely to be dangerous for three main reasons: Nanoparticles may damage the lungs. Nanoparticles can get into the body through the skin, lungs and digestive system. This may help create ‘free radicals’ which can cause cell damage and damage to the DNA.

What is Chlorin e6?

Chlorin e6 is a naturally occurring chlorin commonly used as a photosensitizer. Chlorin e6 has been examined as a nanotechnology delivery tool. Solubility : Soluble in DMSO. Store at -20° C.

Why are photosensitizers added to polymers?

Photosensitizers can induce the generation of singlet oxygen (1O2) under light irradiation. It is known that 1O2 is very reactive and can function as a strong oxidant. Most of the reported photosensitizers are small conjugated molecules,1 whereas polymeric analogs are rarely explored.

Who is the ideal patient for photodynamic therapy?

Ideal candidates for PDT usually have lighter or fair skin that exhibits sun damage, particularly scaly spots called actinic keratosis. You may not be a good candidate if you are sensitive to light or taking any type of medication that might bring on skin irritation during light-based therapies.

What are the disadvantages of nanotechnology to the fields of medicine?

Nanotechnology can even be used in the future to treat lifethreatening diseases like cancer. However, it does have some drawbacks, for example, toxicity, environmental harm and organ damage caused by nanoparticles.

What are the dangers of using nanotechnology?

What are the possible dangers of nanotechnology?

Nanoparticles may damage the lungs.
Nanoparticles can get into the body through the skin, lungs and digestive system.
The human body has developed a tolerance to most naturally occurring elements and molecules that it has contact with.
