Synthesis, Characterization, and SERS Functionalization of Hollow Gold Nanoparticles
Hollow gold nanoparticles formed by galvanic replacement reactions have been extensively studied because their increased surface area and tunable optical properties have applications in catalysis, drug delivery, and photothermal cancer therapies. In this study, hollow gold nanoparticles (size 30-40 nm) were synthesized by transmetallation of tyrosinereduced sacrificial solid silver nanospheres....
متن کاملOptical aggregation of gold nanoparticles for SERS
Optical forces are used to aggregate plasmonic nanoparticles and create SERS-active hot 17 spots in liquid. When biomolecules are added to the nanoparticles, high sensitivity SERS detection 18 is accomplished. Here we tailor this methodology to detect catalase and hemoglobin, two Raman 19 resonant biomolecules, at concentrations down to 10 nM and 1 pM. Subsequently, we study the 20 SERS signal ...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولHeparin Assisted Photochemical Synthesis of Gold Nanoparticles and Their Performance as SERS Substrates
Reactive and pharmaceutical-grade heparins were used as biologically compatible reducing and stabilizing agents to photochemically synthesize colloidal gold nanoparticles. Aggregates and anisotropic shapes were obtained photochemically under UV black-light lamp irradiation (λ = 366 nm). Heparin-functionalized gold nanoparticles were characterized by Scanning Electron Microscopy and UV-Vis spect...
