Synthesis of Silver Nanoparticles

There are many advantages of albumin-based nanoparticles to facilitate their clinical applications and the success of Abraxane is the most excellent example. Encouraged by the success of Abraxane, numerous studies have explored various albumin-based nanoparticles and their applications in various areas, including drug delivery, bioimaging and theranostics.

There are generally two types of albumin used in constructing nanoparticles: human serum albumin (HSA) and bovine serum albumin (BSA). Both kinds of albumin are serum albumin proteins (from human serum and cow serum, respectively) and share a lot of properties, including high solubility in water, long half-life in blood, similar molecular weight (65-70 kDa), similar number of amino acid residues (585 amino acids for HSA and 583 amino acids for BSA) [, ]. There are no observable differences of properties in constructing nanomedicine. Thus, both kinds of albumin have been widely used in designing multifunctional nanoparticles. The developed technologies with alternative albumin could be easily replaced. Thus, the introduction including both kinds of albumin will give a thorough summary and clear route on the developing technologies of albumin-based nanomedicine.

a) Schematic of the effects of albumin corona on the nanoparticles Various plasma proteins are adsorbed onto the nanoparticles after they are injected into the blood; the albumin corona around the nanoparticle inhibits the adsorption of plasma proteins. b) The scheme of albumin-stabilized magnetic nanoparticle and its multifunctional applications in biomedicine. Figure (b) adapted with permission from [].

On the basis of the high biocompatibility and long blood circulation half-life of albumin, many studies have been devoted to the development of albumin-stabilized nanoparticles for biomedical applications [-]. Albumin could be introduced during nanoparticle synthesis or stabilizer replacement [-].

Synthesis of silver nanoparticles and their optical properties

The silver ions form metal nanoparticles, which demonstrate surface plasmon absorption at the wavelength of 425–580 nm.

Albumin could coordinate with metal ions and form QDs, but not all the formed inorganic nanoparticles are fluorescent. Some inorganic nanoparticles are non-fluorescent but possess other attractive properties for biomedical applications. The albumin-templated non-fluorescent inorganic nanoparticles might be used for MRI, photoacoustics, photothermal conversion, or their combinations []. Further modifications on the surface of albumin could endow the nanoparticle with more functions and result in multifunctional nanoparticles for multi-modal imaging, combinational therapy and theranostics [].

AB - Nanostructured materials, especially nanoparticles (NPs), of noble metal NPs such as silver (Ag) have been the focus of research in recent decades because of their distinct physical, chemical, and biological properties. These materials have attracted considerable attention because of their potential applications, such as catalysis, biosensing, drug delivery, and nanodevice fabrication. Previous studies on Ag NPs have clearly demonstrated that their electromagnetic, optical, and catalytic properties are strongly influenced by their shape, size, and size distribution, which can be varied by using different synthetic methods, reducing agents, and stabilizers. The valuable optical properties of Ag NPs have allowed for new approaches in sensing and imaging applications, offering a wide range of detection modes, such as colorimetric, scattering, and surface-enhanced Raman scattering techniques, at extremely low detection limits. Here, an overview of the various chemical, physical, and biological properties of Ag NP fabrication approaches to obtain the various shapes and sizes is presented. The synthesis of Ag nanoparticles (NPs) and the ability to control size, shape, and crystalline structure of NPs during fabrication have important roles in numerous applications. Ag NPs can be produced by fabrication methods such as chemical reduction, electrochemical, γ-radiation, and laser ablation. Single-crystalline Ag nanostructures, including dendrites, dendritic flowers, cactus-like rods, and wires, are successfully synthesized.

Synthesis and optical properties of colloidal gold nanoparticles

Hypoxia is regarded as a key feature of the tumor microenvironment that significantly influences tumor treatment response. An albumin-stabilized gold nanoparticle was synthesized for tumor hypoxia imaging (Figure a) []. The nanoparticle was modified with hypoxia-sensitive nitroimidazole moiety, which was converted into amine groups in the presence of nitroreductase. Conversion from the nitro group of nitroimidazole to the amino group helped increase the zeta potential of the prepared nanoparticle, which thereby improved cell internalization for accumulation at the tumor . The designed nanoparticle displayed enhanced X-CT imaging for tumor hypoxia

Photosensitizers could be loaded into albumin-based nanoparticles through intermolecular disulphide bond reconstruction and hydrophobic interaction, which both exhibited excellent redox response and enhanced tumor targeting []. Mild hyperthermia helped improve ROS generation for promoting PDT. The intrinsic fluorescence and photoacoustic properties of photosensitizers, combined with the chelating characteristic of porphyrin rings, resulted in triple-modal imaging functions of NIRF, MRI and photoacoustic tomography. Upon application of low-energy NIR light irradiation, tumors became completely suppressed, and no tumor recurrence was observed. The loading of mitochondria-targeted photosensitizers in albumin-based nanoparticles improved ROS generation considerably, which lead to mitochondrial disruption and cell apoptosis []. Compared with albumin-based nanoparticles loaded with non-mitochondria-targeted photosensitizers, the nanoparticles loaded with mitochondria-targeted photosensitizers demonstrated a higher phototoxicity against cancer cells and significantly higher tumor growth suppression.
