“…The value of temperature in water bath and conical flask was recorded every 2 min by thermometer. The temperature increased as a function of time along the reaction process is shown in Figure S1b, and the power of ultrasound dissipated inside the conical flask was calculated by the following equation [29] :…”

“…In comparison with conventional reduction protocols, the sonochemical synthesis generally leads to the formation of smaller NPs due to cavitation effects, which determine faster and more intense reactions within transient “micro-reactors” (ultrasound-generated bubbles within the aqueous solution), thus limiting growth and encouraging nucleation processes [ 71 , 72 ]. Besides being thicker, the organic layers formed in the case of Ag@SU and Ag@CU were more dense and compact, which proved the beneficial role of ultrasound cavitation for the dispersion of EO’s molecules [ 73 , 74 ] and resulted in a reduced particle aggregation.…”

The beneficial synergy between antimicrobial silver nanoparticles (AgNPs) and essential oils (EOs), with therapeutic effects that have been acknowledged and explored for a long time, opens the way towards developing new and promising alternatives for anti-infective therapies. With the aim to improve the cytocompatibility and stability of AgNPs and to overcome the volatilization of EOs, AgNPs conjugated with sage (Salvia officinalis) and cinnamon (Cinnamomum aromaticum) EOs were obtained in our study. The synthesis process was realized either by classical or ultrasound-assisted chemical reduction. Compositional and microstructural characterization of the as-obtained Ag@EO NPs was performed by X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The biodistribution of Ag@EO NPs was evaluated on a mouse animal model.

“…In wet chemistry NP synthesis, a metal ion precursor, such as AgNO 3 and Cu(NO 3 ) 2 , is reacted with a reducing agent, such as ethylene glycol (EG) or ascorbic acid in solution with a capping agent, such as PVP and SDS [ 85 ]. In addition to wet chemical synthesis, NPs may also be formed through physical methods, such as evaporation condensation [ 95 ] and laser ablation [ 96 ], additional chemical methods, such as microemulsion [ 97 ], UV or other photonic source initiated photoreduction [ 98 ], electrochemical synthesis [ 84 ], irradiation [ 99 ], microwave-assisted synthesis [ 100 ], and biosynthesis techniques, either through bacteria, fungi, algae or plants [ 100 ]. Spherical metal NPs tend to agglomerate strongly because of their large surface areas, strong interparticle attractions, and particle symmetry regardless of orientation.…”

Recent Advances in High-Throughput Nanomaterial Manufacturing for Hybrid Flexible Bioelectronics

Hybrid flexible bioelectronic systems refer to integrated soft biosensing platforms with tremendous clinical impact. In this new paradigm, electrical systems can stretch and deform with the skin while previously hidden physiological signals can be continuously recorded. However, hybrid flexible bioelectronics will not receive wide clinical adoption until these systems can be manufactured at industrial scales cost-effectively. Therefore, new manufacturing approaches must be discovered and studied under the same innovative spirit that led to the adoption of novel materials and soft structures. Recent works have taken mature manufacturing approaches from the graphics industry, such as gravure, flexography, screen, and inkjet printing, and applied them to fully printed bioelectronics. These applications require the cohesive study of many disparate parts. For instance, nanomaterials with optimal properties for each specific application must be dispersed in printable inks with rheology suited to each printing method. This review summarizes recent advances in printing technologies, key nanomaterials, and applications of the manufactured hybrid bioelectronics. We also discuss the existing challenges of the available nanomanufacturing methods and the areas that need immediate technological improvements.
