Did you mean Polymeric Nanoparticles?

GlossaryPolymeric Nanoparticles

tiny polymer-based particles used for targeted drug delivery

Polymeric Nanoparticles (often abbreviated as Polymeric NPs) are tiny particles made from polymers, which are large molecules composed of repeating subunits. These nanoparticles are typically less than 1,000 nanometers in size and can be engineered to deliver drugs, genes, or other therapeutic agents directly to specific cells or tissues in the body. This targeted delivery system can improve the efficacy and reduce the side effects of treatments, making them particularly useful in medical applications, including treatments for conditions like alopecia.

community Does anyone know the chemical formula for pelage pp405?

in Research/Science 14 upvotes 1 year ago

The conversation discusses the lack of public information on the chemical structure of PP405, a hair loss treatment, and the challenges of synthesizing it without a patent. It also explores a patent related to hydrogen-based topical formulations for reducing oxidative stress and inflammation.

community Since there is so much hype for cosmeRNA and HMI-115...

in Chat 49 upvotes 2 years ago

Exploring different treatments for hair loss, such as cosmeRNA and HMI-115 which are small interference messenger RNA that inhibits the DHT receptor and an antibody that binds to the prolactin (PRL) receptor respectively; and researching mechanism and environment of hyperresponders.

community Topical Finasteride that doesn’t go systematic is the cure

in Treatment 3 upvotes 1 year ago

Topical finasteride that doesn't penetrate the skin could potentially treat hair loss without side effects. Current challenges include finding a formulation that remains on the scalp without increasing blood levels.
