Cellulose nanocrystals (CNCs), or nanocrystalline cellulose (NCC), are highly crystalline, rod-like nanoparticles. [6] [7] They are usually covered by negatively charged groups that render them colloidally stable in water. They are typically shorter than CNFs, with a typical length of 100 to 1000 nanometers. [8]
Capsules formed from cellulose sulphate have been successfully used, showing safety and efficacy, in clinical and pre-clinical trials in both humans and animals, primarily as anti-cancer treatments, but also exploring possible uses for gene therapy or antibody therapies.
Over the course of the treatment, gold nanoparticle can make the skin appear smoother and even in color. [22] A study in 2010 titled, "Novel Vitamin and Gold-Loaded Nanofiber Facial Mask for Topical Delivery" investigated how gold nanoparticle can be incorporated to facial mask along with Vitamin C (L-ascorbic acid), retinoic acid , and ...
[12] [58] Localized argyria can occur as a result of topical use of silver-containing creams and solutions, while the ingestion, inhalation, or injection can result in generalized argyria. [59] [60] Preliminary reports of treatment with laser therapy have been reported. These laser treatments are painful and general anesthesia is required.
Argyria and staining: Ingested silver or silver compounds, including colloidal silver, can cause a condition called argyria, a discoloration of the skin and organs.In 2006, there was a case study of a 17-year-old man, who sustained burns to 30% of his body, and experienced a temporary bluish-grey hue after several days of treatment with ...
Cellulose sulfate (also known as sulfate cellulose or sulfocellulose) The polyanion category of microbicides includes the carrageenans. Carrageenans are a family of linear sulfated polysaccharides chemically related to heparan sulfate, which many microbes utilize as a biochemical receptor for initial attachment to the cell membrane.
Another system of drug delivery involving nanoparticles is the use of aquasomes, self-assembled nanoparticles with a nanocrystalline center, a coating made of a polyhydroxyl oligomer, covered in the desired drug, which protects it from dehydration and conformational change.
A nanocrystalline (NC) material is a polycrystalline material with a crystallite size of only a few nanometers. These materials fill the gap between amorphous materials without any long range order and conventional coarse-grained materials. Definitions vary, but nanocrystalline material is commonly defined as a crystallite (grain) size below ...
