Burns are the most common and devastating form of wounds and are usually accompanied by abnormal inflammation, inadequate extracellular matrix production, reduced angiogenesis, and lack of growth factor stimulation, which can significantly delay wound healing and lead to complications. Pearl powder, a traditional Chinese medicine, has been used to treat wound healing. In the present study, we found that supercritical CO extracted pearl peptides in the size range of ">10kd" have great potential to promote wound healing at the cellular level.

In this study, we fabricated gold nanoparticle-decorated GO (GO-Au) nanocomposites and characterized their physicochemical properties using UV-Vis absorption spectra, FTIR spectra, contact angle analyses, and free radical scavenging potential. Moreover, we investigated the potent applications of GO-Au nanocomposites on directing mesenchymal stem cells (MSCs) for tissue regeneration.

The traditional industrial extraction processes of pearl powder are mainly based on water, acid or enzyme extraction methods, all of which have their own drawbacks. In this study, we propose a new extraction process for these active ingredients, specifically, water-soluble components of pearl powder extracted by a CO supercritical extraction system (SFE), followed by the extraction efficiency evaluation.

While used for over a thousand years, there has yet to be an in-depth understanding and review in this area. The use of pearl powder is particularly growing in the biomedical area with various benefits reported due to the active ingredients within the pearl matrix itself.

Pearl powder is a powdery substance by grinding pearls into small grains, however, the nacre powder is the inner layer of outer corner layer and middle prism layer. Pearl medicine in China has a history of more than 2,000 years, pearl has the effects of calming the mind, clearing the eyes, detoxifying the muscle and so on.
