Inkjet-printed photodetectors have gained enormous attention over the last decade. However, device performance is limited without post-processing, such as annealing and UV exposure. In addition, it is difficult to manipulate the surface morphology of the printed film using an inkjet printer due to the limited options of low viscosity ink solutions. Here, we employ a concept involving the control of the inkjet-printed film morphology via modulation of co-solvent 2 vapor pressure and surface tension for the creation of a high-performance ZnO-based photodetector on a flexible substrate. The solvent boiling point across different co-solvent systems is found to affect the film morphology, which results in not only distinct photo-response time but also photo-detectivity. ZnO-based photodetectors were printed using different solvents which display a fast photo-response in low-boiling point solvents due to the low carbon residue and larger photo-detectivity in high-boiling point solvent systems due to the porous structure. The porous structure is obtained using both gas-liquid surface tension differences and solid-liquid surface differences, and the size of porosity is modulated from nano-size to micro-size depending on the ratio between two solvents or two nanomaterials. Moreover, the conductive nature of graphene enhances the transport behavior of the photocarrier, which enables a high-performance photodetector with high photo-responsivity (7.5*10 2 AW-1) and fast photo-response (0.18 s) to be achieved without the use of high-boiling point solvents. section image of printed thin films (Figure S6); the detail information of device preparation and characterisation methods; SEM (Figure S7) and AFM images (Figure S8) of as-printed thin films;

“…These NPs can be synthesized so as to contain therapeutic agents in high concentrations that can be released in a targeted manner [25,26]. For instance, several studies focused on the production and practical applications of poly (methyl methacrylate) (PMMA) dispersions [27,28]. PMMA, a commonly used amorphous synthetic polymer, appears to be promising for biomedical applications due to its lack of toxicity, low cost, minimal inflammatory reactions on tissues and simple processability [29].…”

Metal nanoparticles (NPs) have garnered considerable attention, due to their unique physicochemical properties, that render them promising candidates for various applications in medicine and industry. This article offers a comprehensive overview of the most recent advancements in the manufacturing, characterization, and biomedical utilization of metal NPs, with a primary focus on silver and gold NPs. Their potential as effective anticancer, anti-inflammatory, and antimicrobial agents, drug delivery systems, and imaging agents in the diagnosis and treatment of a variety of disorders is reviewed. Moreover, their translation to therapeutic settings, and the issue of their inclusion in clinical trials, are assessed in light of over 30 clinical investigations that concentrate on administering either silver or gold NPs in conditions ranging from nosocomial infections to different types of cancers. This paper aims not only to examine the biocompatibility of nanomaterials but also to emphasize potential challenges that may limit their safe integration into healthcare practices. More than 100 nanomedicines are currently on the market, which justifies ongoing study into the use of nanomaterials in medicine. Overall, the present review aims to highlight the potential of silver and gold NPs as innovative and effective therapeutics in the field of biomedicine, citing some of their most relevant current applications.

“…The first issue is that the hydrophilicity of MMA is stronger than that of St, and thus the monodispersity and sphericity of PMMA nanospheres are more difficult to control than those of PS nanospheres when synthesizing a high mass fraction of PMMA colloidal nanospheres on a large scale. 29,30 The second issue is that, when attempting to increase the mass fraction of the colloidal PMMA nanospheres to prepare PMMA-based LPCs, the nanospheres are prone to agglomerate due to their collision and coalescence. The third issue is that the structural stability of PMMA photonic crystals constructed by using common methods is not good enough for practical applications, since PMMA nanospheres have a rigid structure and the binding between them primarily relies on weak interactions such as van der Waals forces and hydrogen bonding, leading to disruption of the PC structure easily under external forces and thus color attenuation or even complete disappearance of the structural color.…”
