“…The commonly used bottom-up approaches include chemical synthesis and biological synthesis, both can obtain NPs by reducing the precursor salt 52 . The chemical synthesis can be coupled with alternative energies, such as photochemical 53 , electrochemical 54 , microwave-assisted 55 and sonochemical methods 12 . Though the chemical method is carried out to quickly obtain various shapes of NPs, the use of harmful chemical additives may limit the medical applications of NPs.…”

Silver nanoparticles (AgNPs) have been one of the most attractive nanomaterials in biomedicine due to their unique physicochemical properties. In this paper, we review the state-of-the-art advances of AgNPs in the synthesis methods, medical applications and biosafety of AgNPs. The synthesis methods of AgNPs include physical, chemical and biological routes. AgNPs are mainly used for antimicrobial and anticancer therapy, and also applied in the promotion of wound repair and bone healing, or as the vaccine adjuvant, anti-diabetic agent and biosensors. This review also summarizes the biological action mechanisms of AgNPs, which mainly involve the release of silver ions (Ag + ), generation of reactive oxygen species (ROS), destruction of membrane structure. Despite these therapeutic benefits, their biological safety problems such as potential toxicity on cells, tissue, and organs should be paid enough attention. Besides, we briefly introduce a new type of Ag particles smaller than AgNPs, silver Ångstrom (Å, 1 Å = 0.1 nm) particles (AgÅPs), which exhibit better biological activity and lower toxicity compared with AgNPs. Finally, we conclude the current challenges and point out the future development direction of AgNPs.

“…However, during chemical synthesis, the concentration of precursors changes, complicating the controlled formation of nanoparticles in shape and size. Therefore, as an alternative, electrochemical production of AgNPs [6][7][8][9][10][11][12][13] is promising, where the value of the electrode potential or current density is an effective factor in influencing the geometry of nanoparticles and their size distribution.…”

“…To ensure a constant concentration of silver ions in the reaction medium and to avoid contamination of the solutions with 3 NOanions, electrolysis is performed using soluble anodes [6][7][8][9][10][11][12][13]. The anode solubility depends on the nature of the surfactant; they act as stabilizers for AgNPs.…”

“…However, the anodic behavior of silver in solutions of surfactants stabilizers has not been practically studied, which makes it difficult to control the concentration of Ag + ions. In addition, the controlled provision of the active state of silver anodes becomes more complex, which leads to their passivation and the need to carry out electrolysis with variable polarity [8,13]. Anodic dissolution of silver is also used to synthesize silver complexes with surfactant molecules as precursors of AgNPs [9].…”

“…It allows you to regulate the formation of the geometry of nanoparticles and eliminates the need to use chemical reducing agents. Despite the widespread use for the stabilization of metals nanoparticles surfactants of natural origin [1][2][3][12][13][14][15], studies on the possibility of their use in the electrochemical synthesis of MNPs are relevant.…”

Silver anodic dissolution in aqueous solutions of rhamnolipid (RL) has been investigated depending on the following parameters: concentration of RL, temperature, pH of medium and scanning speed of anode potential. It is shown that the active dissolution occurs at Е > 0.4 V in a wide range of concentrations of the surfactant at t = 20-50 °C. With an increase in the concentration of rhamnolipid and temperature, the anode currents increase almost linearly with E = 0.4-1.0 V. They also increase with an increase in pH from 7 to 10.
