Biomolecules such as L-aspartic acid can be well-reducing and capping agents to produce metal nanoparticles with unique bioapplications. Silver nanoparticles (AgNPs) were synthesized using L-aspartic acid and evaluated as antibacterial and anticancer agents. The L-aspartic acid-AgNPs were characterized by utilizing spectroscopic instruments. Ultrav...

One of the most prevalent transformations in organic chemistry is the production of amide bonds by chemical processes. Seven new long alkyl amide compounds were produced in this study using a direct reaction.
