Gold Nanoparticles in Nanobiotechnology: From Synthesis to Biosensing Applications

“…The nanoparticles demonstrated a wide range of forms, such as spheres, triangles, and quasi-hexagons, which present a favorable potential for utilization in the hemoglobin or protein electrochemistry . In addition, it has been observed that Rhodobacter capsulatus , a bacterium capable of photosynthesis, exhibits an enhanced ability to adsorb HAuCl 4 and demonstrates the capability to reduce trivalent gold . The involvement of carotenoids and NADPH-dependent enzymes, whether integrated into plasma membranes or discharged into the extracellular environment, has been recognized as crucial in the biosorption and bioreduction mechanisms of Au 3+ to Au 0 .…”

Gold Nanomaterials-Based Electrochemical Sensors and Biosensors for Phenolic Antioxidants Detection: Recent Advances

“…The corresponding synthetic procedure is generally divided into two parts: The intracellular biosynthesis and the extra-cellular biosynthesis. The results seem to be very promising, but the experimental protocols require some improvement to optimize these innovative and green synthetic approaches [ 40 , 41 ].…”

“…In order to deepen the topic, we suggest several particularly meaningful reviews and papers [ 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ], including an interesting example of a hybrid organic–inorganic metal nanoparticles application to develop a localized surface plasmon resonance (LSPR)-based biosensor for antibiotics detection [ 47 ].…”
