ÖZAmaç: Bulaşıcı hastalıkların yayılması ve mikroplar arasında gözlenen ilaç direncindeki artış, araştırmacıları biyolojik olarak aktif nanopartikülleri sentezlemeye zorladı. Nanopartiküllerin sentezine yönelik çevre dostu prosedürler, nanobiyoteknoloji alanında her geçen gün gelişmektedir. Bu çalışmada palladyum ve platin nanopartiküllerin sentezi için yeşil bir alg olan Botryococcus braunii ekstraktını kullandık ve nanopartiküllerin antimikrobiyal ve antioksidan aktivitelerini değerlendirdik. Gereç ve Yöntemler: Udaisagar Gölü, Udaipur'dan (Rajasthan, Hindistan) yeşil alg toplandı ve seri seyreltme yöntemiyle izole edildi ve Chu-13 besi yerinde büyütüldü. Alg tarafından sentezlenmiş paladyum ve platin nanopartiküllerinin karakterizasyonu, X-ışını kırınımı ve taramalı elektron spektroskopisi kullanılarak gerçekleştirildi. İnhibisyon alanı, agar difüzyon tekniği kullanılarak ölçüldü ve minimum inhibitör konsantrasyonu, antimikrobiyal aktivite için agar seyreltme deneyi ile belirlendi. Nanopartiküllerin antioksidan aktivitesi de 1,1-difenil-2-picrylhydrazyl yöntemi ile belirlendi. Bulgular: Kararlı paladyum ve platin nanoparçacıklar yeşil alg kullanılarak başarılı bir şekilde üretildi. XRD paterni, kristalin yapıyı doğruladı ve taramalı elektron mikroskobu mikrografları, biyolojik olarak sentezlenen metal nanoparçacıkların morfolojisini gösterdi. fourier dönüşümü Objectives: The spread of infectious diseases and the increase in drug resistance among microbes has forced researchers to synthesize biologically active nanoparticles. Ecofriendly procedures for the synthesis of nanoparticles are improving day by day in the field of nanobiotechnology. In the present study we used extract of the green alga Botryococcus braunii for the synthesis of palladium and platinum nanoparticles and evaluated their antimicrobial and antioxidant activity. Materials and Methods: Green alga was collected from Udaisagar Lake, Udaipur (Rajasthan, India) and isolated by serial dilution method and grown on Chu-13 nutrient medium. The characterization of alga synthesized palladium and platinum nanoparticles was carried out using X-ray diffraction and scanning electron spectroscopy. The zone of inhibition was measured by agar well plate method and minimum inhibitory concentration was determined by agar dilution assay for antimicrobial activity. The antioxidant activity of the nanoparticles was also studied by 1,1-diphenyl-2picrylhydrazyl method. Results: Stable palladium and platinum nanoparticles were successfully produced using green alga. The XRD pattern revealed the crystalline nature and scanning electron micrographs showed the morphology of biogenically synthesized metal nanoparticles. Fourier transform infrared measurements showed all functional groups having control over stabilization and reduction of the nanoparticles. The green synthesized nanoparticles exhibited antimicrobial activity against gram-positive and gram-negative bacterial strains, antifungal activity against a fungus, and antioxidant activity. Conclusion: The biogenic s...

“…The conversion and formation of PtNPs was confirmed by rapid color changes at an elevated temperature of 95 • C, which represented the formation of PtNPs. The Antigonon leptopus extract acted as a stabilizing and reducing agent for the synthesis of PtNPs [96]. PtNPs have been synthesized using leaf extract from Barleria prionitis.…”

Platinum nanoparticles (PtNPs) are noteworthy scientific tools that are being explored in various biotechnological, nanomedicinal, and pharmacological fields. They are unique because of their large surface area and their numerous catalytic applications such as their use in automotive catalytic converters and as petrochemical cracking catalysts. PtNPs have been widely utilized not only in the industry, but also in medicine and diagnostics. PtNPs are extensively studied because of their antimicrobial, antioxidant, and anticancer properties. So far, only one review has been dedicated to the application of PtNPs to nanomedicine. However, no studies describe the synthesis, characterization, and biomedical application of PtNPs. Therefore, the aim of this review is to provide a comprehensive assessment of the current knowledge regarding the synthesis, including physical, chemical, and biological and toxicological effects of PtNPs on human health, in terms of both in vivo and in vitro experimental analysis. Special attention has been focused on the biological synthesis of PtNPs using various templates as reducing and stabilizing agents. Finally, we discuss the biomedical and other applications of PtNPs.

“…These exciting compounds can take part both in the reduction of platinum ions to Pt 0 and stabilization against agglomeration [ 23 , 79 , 80 , 81 ]. Flavonoids, tannins, glycosides, alkaloids, steroids, terpenoids, saponins, polysaccharides, proteins and enzymes can be represented as such agents ( Table 1 ) [ 35 , 73 , 74 , 78 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 ]. The bio reduction pathway is heavily influenced by functional groups such as amine (–NH), alcohol (–OH), and carboxylic group (–COO).…”

The diverse biological properties of platinum nanoparticles (PtNPs) make them ideal for use in the development of new tools in therapy, diagnostics, and other biomedical purposes. “Green” PtNPs synthesis is of great interest as it is eco-friendly, less energy-consuming and minimizes the amount of toxic by-products. This review is devoted to the biosynthesis properties of platinum nanoparticles based on living organisms (bacteria, fungi, algae, and plants) use. The participation of various biological compounds in PtNPs synthesis is highlighted. The biological activities of “green” platinum nanoparticles (antimicrobial, anticancer, antioxidant, etc.), the proposed mechanisms of influence on target cells and the potential for their further biomedical application are discussed.
