New-generation integrated devices based on dye-sensitized and perovskite solar cells for energy harvesting storage are significantly important self-powering systems portable/wearable electronics.
Delivery vehicles: Gold nanoparticles (AuNPs) have been used as a nanocarrier to non-invasively deliver synthetic cytosine–phosphate–guanosine (CpG) oligodeoxynucleotides (ODNs) into cells. Compared unconjugated single-stranded CpG ODNs, self-assembled polyvalent CpG-AuNP conjugates enhance the efficiency of cellular uptake and stimulate secretion cytokines (see picture).
