“…For multiple purposes, they are engineered into highly stable colloidal suspensions, and using different surface functionalization procedures, they show biocompatibility and colloidal stability in physiological conditions and in vivo assays [3,4]. Consequently, this nanomaterial has recently found meaningful applications in cell imaging and therapeutic processes in addition to different types of optoelectronic devices such as biosensors, solar cells, and surface-enhanced Raman spectroscopy, as well as in photocatalysis [5][6][7][8][9][10][11][12]. In the biomedical field, AuNPs have been used in electrochemical dopamine sensors [13] and intensified in early diagnosis of Parkinson's disease [14].…”

Eco-friendly chemical methods using FDA-approved Pluronic F127 (PLU) block copolymer have garnered much attention for simultaneously forming and stabilizing Au nanoparticles (AuNPs). Given the remarkable properties of AuNPs for usage in various fields, especially in biomedicine, we performed a systematic study to synthesize AuNP-PLU nanocomposites under optimized conditions using UV irradiation for accelerating the reaction. The use of UV irradiation at 254 nm resulted in several advantages over the control method conducted under ambient light (control). The AuNP-PLU-UV nanocomposite was produced six times faster, lasting 10 min, and exhibited lower size dispersion than the control. A set of experimental techniques was applied to determine the structure and morphology of the produced nanocomposites as affected by the UV irradiation. The MTT assay was conducted to estimate IC50 values of AuNP-PLU-UV in NIH 3T3 mouse embryonic fibroblasts, and the results suggest that the sample is more compatible with cells than control samples. Afterward, in vivo maternal and fetal toxicity assays were performed in rats to evaluate the effect of AuNP-PLU-UV formulation during pregnancy. Under the tested conditions, the treatment was found to be safe for the mother and fetus. As a proof of concept or application, the synthesized Au:PLU were tested as contrast agents with an X-ray computed tomography scan (X-ray CT).

“…AuNPs allow light to linger inside the cell over longer distances by scattering Sunlight. [22][23][24][25][26][27][28][29] Additionally, the quantities and qualities of localized surface plasmon resonance depend on the shape and dimension, morphology, spacing size, and distribution of nanoparticles. 30,31) Therefore, the deposition of AuNPs has the potential to improve the energy conversion efficiency of c-Si solar cell.…”

In order to increase the photocurrent of tandem solar cells with a silicon (Si) solar cell as the bottom cell, we investigate the relationship between the localized surface plasmon resonance effect of gold nanoparticles (AuNPs) and the arrangement of AuNPs onto solar cells. AuNPs were deposited on P-type crystalline Si (c-Si) cells and Si heterojunction (SHJ) type cells. To obtain the localized plasmon resonance effect, the shape, size, and arrangement of the nanostructures are important. Especially, arrangement of AuNPs onto solar cells was inquired in this study because these parameters must be adjusted appropriately to produce a plasmon resonance in a specific wavelength range. It was found that the plasmon resonance effect is significant when deposited on the surface of c-Si cell rather than on top of the Ag electrode. AuNPs deposition on the c-Si cell surface leads to not only the localized plasmon resonance effect but also improvement in charge transport between the c-Si cell surface and Ag electrode. However, in the SHJ-type cells, the plasmon resonance effect was not observed because the surface layer was composed of a w-doped In2O3 (IWO) layer.
