Herein, we report a novel route to prepare polymorphic carbon dot fluorescent probes via the evaporation-induced self-assembly of glutaraldehyde and carbon dots, which first usually form carbon nanoclusters which then could self-assemble to form carbon nanocrystals, nanospheres or nanofibers in different ionic strength solutions at room temperature.

Spherical Microparticles

Towards the design of bioceramics with control over both macroscopic shape and mesoporosity, silica based mesoporous materials have been synthesized using evaporation-induced self-assembly method by two different routes: room temperature (RT) and aerosol-assisted synthesis (A-A). Two series varying surfactant/silica precursor ratio have been synthesized in order to check the mesopore ordering as a function of the structure directing agent amount in both preparation procedures. The A-A method leads to spherical microparticles, which exhibit mesopore ordering for a wider surfactant/silica range compared with room temperature method, which yield irregular shaped particles. Textural properties values show that for the same surfactant amount, aerosol-assisted method develops higher porosity values in the obtained silica microparticles.

Bimetallic nanoparticles of silver (Ag) and gold (Au) were synthesized at room temperature using Curcumin. Reduction process of silver and gold ions with different molar ratios leads to production of different nanostructures including alloys and core-shells. Produced nanoparticles were characterized simultaneously with FTIR, UV/vis. spectroscopy, transmission electron microscopy (TEM), and Energy-dispersive X-ray (EDAX). UV/vis. optical absorption spectra of as synthesized nanoparticles reveals presence of surface palsmon resonance (SPR) of both silver at (425 nm) and gold at (540 nm) with small shift and broadness of gold band after mixing with resucing and capping agent in natural extract which suggest presence of bimetallic nano structure (Au/Ag). FTIR and EDAX data approve the presence of bimetallic nano structure combined with curcumin extract. TEM micrographs shows that silver and gold can be synthesized separately in the form of nano particles using curcumin extract. Synthesis of gold nano particles in presence of silver effectively enhance and control formation of bi-metallic structure.
