Silver and Gold Nanoparticles: Challenges and Perspectives

Abstract

Syntheses of gold nanoparticles (AuNPs) and silver nanoparticles (AgNPs) were evaluated with an emphasis on controlling the size, shape and stability of nanoparticles (NPs). Various reducing and capping agents of NPs from the sphere of chemistry and biology were identified together with their role in synthesis and controlled NPs properties. Those NPs were characterized with a variety of methods in order to determine the activities of nanoparticles and their applications in real life. In addition, carriers of these NPs in-vitro and in-vivo investigations and models of nanoscale interactions are presented. This review also addresses systematically the biomedical applications of AuNPs and AgNPs taking into account the actual challenges and perspectives in this research field.

Forsterite as an Alternative for Orthopaedic Implants – Short Review

“…Another study niche could be the functionalization of forsterite with different metallic nanoparticles [113][114][115][116][117][118][119][120][121][122][123][124][125][126][127][128][129][130][131] and biologically active molecules, which improve upon forsterite properties.…”

Effects of Spherical and Rod-like Gold Nanoparticles on the Reactivity of Human Peripheral Blood Leukocytes

“…GNPs are mainly prepared according to the post-reduction reaction of tetrachloroauric acid (HAuCl 4 ) in a liquid medium, although they can also be obtained using photochemical methods or methods belonging to the field of "green" chemistry [4][5][6][7][8][9][10][11][12][13][14][15].…”

“…Gold nanoparticles (GNPs) are characterized by the ease of their assimilation by cells. As a result, they have found application mainly in the biomedical industry [4][5][6][7][8][9][10][11][12][13][14][15].…”

“…They are used as innovative tools in diagnostic tests, such as in the detection of biomarkers for cardiovascular disease or cancer, as well as in drug delivery systems [4][5][6][7][8][9][10][11][12][13][14][15].…”

Gold Nanoparticles and Chemotherapeutic Agents

“…Considering the unique properties of AuNPs and their potential applications there are already a great number of review papers tackling an in-depth study of synthesis methods and recent advances in cancer therapies and drug delivery [27][28][29][30][31]. However, a review regarding AuNPs and different types of chemotherapeutic agents has not yet been done, taking into account various models of nanoscale interactions.…”
