ABSTRACTThe synthesis of biocompatible noble metal nanoparticles dispersible in a wide range of biological media with control of polycrystalinity and nanogeometry, pH sensitivity and salt tolerance has been a challenging requirements. The role of 3-aminopropyltrimethoxysilane (3-APTMS) and organic reducing reagents for real time synthesis of amphilic noble metal nanoparticles meeting these requirements are demonstrated justifying the following; (1) 3-APTMS capped noble metal ions are converted into respective metal nanoparticles in the presence of one of organic reducing agents i.e., cyclohexanone, tetrahydrofuran hydroperoxide (THF-HPO), formaldehyde, acetaldehyde, acetone, t-buty dimethyl keotone, 3-Glycidoxy-propyltrimethoxysilane (3-GPTMS); (2) 3-APTMS acts as micelle, promotes the interaction of metal ions with organic reducing agent, precisely controls the size of metal nanoparticles, pH sensititvity and salt tolerance and also provides a suitable medium for nanoparticles suspension, (3) the use of suitable organic reagent precisely controls the polarity of as made noble metal nanoparticles allowing specific biological interactions, and (4) 3-APTMS significantly increases the stability and controls the pH sensitivity and salt tolerance of metal nanoparticles. The as synthesized nanomaterials show potential viability in biomedical applications from many angles i.e. (a) as potential bioelectrocatalyst, (b) selective interaction with active proteins and cellular components, and (c) peroxidase mimetic.

AbstractDeep eutectic solvents (DESs) were developed 15 years ago and have been used for various purposes based on their unique chemical and physical properties. Recently, they have been highlighted as versatile media for the synthesis of noble metal nanomaterials. Although there are a few limitations, their vast chemical library of hydrogen bond donors and excellent solubility show great potential for their future applications for the synthesis of noble metal nanoparticles.

Nanotechnology has prompted new and improved materials for biomedical applications with particular emphasis in therapy and diagnostics. Special interest has been directed at providing enhanced molecular therapeutics for cancer, where conventional approaches do not effectively differentiate between cancerous and normal cells; that is, they lack specificity. This normally causes systemic toxicity and severe and adverse side effects with concomitant loss of quality of life. Because of their small size, nanoparticles can readily interact with biomolecules both at surface and inside cells, yielding better signals and target specificity for diagnostics and therapeutics. This way, a variety of nanoparticles with the possibility of diversified modification with biomolecules have been investigated for biomedical applications including their use in highly sensitive imaging assays, thermal ablation, and radiotherapy enhancement as well as drug and gene delivery and silencing. Here, we review the available noble metal nanoparticles for cancer therapy, with particular focus on those already being translated into clinical settings.
