“…Indeed, the AuNPs can provide many favourable properties to a drug, especially including a longer elimination time, an increased drug-site contact time, and a reduced drug resistance [6,7]. There are many methods used to produce the AuNPs in the laboratory settings, counting the chemical reduction [8], the sol-gel precipitation [9], and the green synthesis [10]. Unfortunately, all these methods usually involve the multi-step processes and complex chemical treatments that require a relatively high labour investment and generate costs.…”

“…Unfortunately, all these methods usually involve the multi-step processes and complex chemical treatments that require a relatively high labour investment and generate costs. Moreover, the efficiency of the synthesis of the AuNPs with the above-mentioned methods can be limited, while the fabricated nanomaterials are still not ready-to-use and commonly need an additional purification before their specific biological or medical applications [10,11].…”

In this work, the gold nanoparticles (AuNPs) were synthesized using pulse-modulated radio-frequency atmospheric pressure glow discharge (pm-rf-APGD). By tailoring selected operating parameters of the pm-rf-APGD reaction-discharge system, the experimental conditions for the synthesis of raw-AuNPs with controlled optical and structural properties were found. The colloidal suspension of the size-controlled raw-AuNPs was mixed with an aqueous solution of gelatine and turmeric oil to produce an oil-in-water (O/W) nanoemulsion. AuNPs loaded into the nanoemulsion were characterized using ultraviolet-visible absorption spectrophotometry, dynamic light scattering, scanning electron microscopy supported by energy dispersive X-ray spectroscopy, and transmission electron microscopy equipped with selected area X-ray diffraction. Additionally, attenuated total reflectance Fourier-transform infrared spectroscopy was used to confirm the efficient functionalization of the AuNPs by nanoemulsion component. It was revealed that AuNPs were mostly spherical with an average size of 4.6 ± 1.0 nm and a face-centered cubic crystal system. The developed O/W nanoemulsion carrying AuNPs was applied towards the human breast cancer cell lines MCF7 and MDA-MB-231. It was found that it exhibited the cytotoxicity towards the breast cancer cells while were non-cytotoxic towards the non-tumour breast cells MCF10A. Moreover, it also inhibited the migration of the invasive cancer breast cells (line MDA-MB-231) and hence, could prevent the breast cancer metastasis.

“…The r 2 for gallic acid in TPC is 0.9997, for quercetin in TFC is 0.9996 while for gallic acid in TTC is 0.9918. The standard curve for TPC, TFC and TTC showed in Fig 1 to Fig 3. In biosynthesizing of nanoparticles, phenolic compounds play an important role for reduction and stabilization [10]. The decrease in absorbance of DPPH radical is caused by antioxidant through the reaction between antioxidant molecule and radical results in the scavenging of the radical by hydrogen donation.…”

In this study, comparative phytochemical analysis of total phenolics content (TPC), total flavonoids content (TFC), total tannins content (TTC) and in vitro analysis of antioxidant assay for DPPH radical scavenging activity and ferric iron reducing assay (FRAP) of two different extracts, from the fruit peels of banana (BP) and pineapple (PIP) were determined using spectrophotometric methods. TPC, TFC, TTC, DPPH antioxidant assay and FRAP assay from methanolic BP extract was higher compared to PIP with the values 2.9330 mg GAE/g of extract, 1.2175 mg QAE/g of extract and 0.1520 mg GAE/g of extract respectively. The antioxidant assay showed higher in BP extract compared to PIP extract with the scavenging activity of 32.18 % and increment of reducing power ability when the concentration increased. BP was chosen to conduct a biosynthesis of nanoparticles which can be applied in many fields.

“…As it was previously mentioned, due to high reactivity with respect to size, there are many types of catalysts in form of nanoparticles. There are catalysts based on nanostructures of iron, gold, platinum, palladium and nickel [3]. Because of the higher efficiency, system based catalyst with nanometric size is proposed.…”

Presented article is based on the concept of autonomous generator of methane which may be potential used in small and medium scale industries for the energy generation. The installation is powered by renewable energy sources, using both the solar and wind energies An essential element of the system is reactor of methane filled by hydrogen and carbon dioxide. Operation of the presented reactor is also supported by a catalytic activity of nanoparticles, which can be synthesized via a bioreduction process. Methane may be used directly or injected into local distribution network, also may support local cogeneration installations. In the article, it is described in details all stages of the whole process leading to the methane generation. The possibility of cooperation between developed solution and the national energy system is also discussed.
