Anisotropic Gold-based Nanoparticles: Preparation, Properties, and Applications

Abstract

Among the several types of nanoparticles in existence, anisotropic gold-based nanoparticles demonstrate special advantages because of their unique properties. Gold nanoparticles can be prepared and modified with a wide range of functional materials including polymers, surfactants, ligands, dendrimers, drugs, DNA, RNA, proteins, peptides, and oligonucleotides. Hence, they are a promising vehicle for bioimaging, drug delivery, and other therapies. This review mainly addresses the properties, preparation, and applications of anisotropic gold nanoparticles in biomedical applications and targeted drug delivery.

Physicochemical Study of the Interaction between Gold Nanoparticles and Lipase from Candida sp. (CALB): Insights into the Nano-Bio Interface

“…[8][9][10] Furthermore, AuNPs are attractive because they can be prepared with different morphologies and have their surface modified by simple and straightforward methods employing a huge variety of biomolecules such as amino acids, peptides, proteins, enzymes, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), among others. [11][12][13][14] Based on these reasons and for prospecting new eco-friendly approaches, biomolecules have been used as suitable capping agents for AuNPs. [15][16][17] Nevertheless, despite the increasing interest in this field, few studies are reported in the literature 16,[18][19][20] using enzymes as the interacting molecules for AuNPs.…”

Gold Nanorods as Nanodevices for Bioimaging, Photothermal Therapeutics, and Drug Delivery

“…20,21) Further detailed information for the synthesis of gold nanorods by chemical reaction is available in several review papers. 4,5,22,23) Photochemical method is an alternative means to synthesize uniform gold nanorods using the same reaction solution with that of the seeding method. 24,25) In this method, UV light irradiation triggers radical production in the reaction solution.…”
