As people are more exposed to pollution, UV rays, hormonal imbalances and stress, dark skin, pigmentation, melasma and dullness are quite common
Several studies report the formation of stable CQD-Ct-DNA complexes capable of intracellular delivery in L929 and MCF-7 cell lines, allowing fluorescent monitoring of gene transport, moreover, suggesting potential applications as non-viral vectors for bioimaging-guided gene transport [ Echinophora tenuifolia were shown to selectively stain non-viable cells with high fluorescent intensity and photostability, a property attributed to their negatively charged surface favouring interactions with compromised cellular membranes, sparing viable cells [ From a materials design perspective, the suitability of CQDs for bioimaging is closely linked to synthesis-dependent control over particle size, surface passivation, and heteroatom incorporation
Boring, slow, but properly proven
A clinical trial is underway in patients to see if aspirin is beneficial
