“…In contrast, photosynthesized clusters (blue line spectrum) show an SPR maximum at 585 nm, which is representative of the presence of decahedral structures (average particle size > 20 nm). Please refer to our previous contribution [ 3 ] for a complete nanoparticles synthesis procedure and analysis.…”

“…For testing the AgNPs attachment to the PLA surface, 3D-printed milli-reactors (1 mm channel width) were impregnated in the channels with both synthesized colloids, ( Figure 4 a) (Please refer to a previous contribution [ 3 ] for a complete description of the design and assembly of the 3D-printed milli-reactors and pumping system). In our previous contribution, the 3D-printed reactors did not adsorb NPs when they were pumped across the fluidic system.…”

“…Bigger clusters were synthesized using a 3D-printed reactor illuminated with a green LED light (100 W, IP66) at room temperature [ 3 ]. Briefly, the starting solution was pumped through the reactor ware with an infusion syringe pump (SP-200, Advanced Instrumentation, Miami, FL, USA) for 4 h. Samples were collected and stored in the dark prior to characterization.…”

“…Interest in the additive manufacturing process known as 3D printing has grown in different scientific areas in recent years [ 1 , 2 ], due to the advantages of rapid prototyping, fast design, ease of access, cost effectiveness, among many others. This fast development process has been applied in batch and micro- and milli-fluidic reactors [ 3 , 4 , 5 , 6 ] for chemical synthesis, medical devices [ 7 ], medicine tablets for drug delivery [ 8 , 9 ], 3D-printed scaffolds for tissue engineering [ 10 ], laboratory equipment [ 11 ], analytical and bioanalytical sensors [ 12 ], catalytic systems [ 13 , 14 ], etc. Among several 3D-printing techniques, fused deposition modeling (FDM) appears to be the cheapest, fastest, and most affordable method [ 1 ].…”

Modifying the natural characteristics of PLA 3D-printed models is of interest in various research areas in which 3D-printing is applied. Thus, in this study, we describe the simple impregnation of FDM 3D-printed PLA samples with well-defined silver nanoparticles and an iron metal salt. Quasi-spherical and dodecahedra silver particles were strongly attached at the channels of 3D-printed milli-fluidic reactors to demonstrate their attachment and interaction with the flow, as an example. Furthermore, Fenton-like reactions were successfully developed by an iron catalyst impregnated in 3D-printed stirrer caps to induce the degradation of a dye and showed excellent reproducibility.

Visible light photocatalysis is a rapidly developing branch of chemical synthesis with outstanding sustainable potential and improved reaction design. However, the challenge is that many particular chemical reactions may require dedicated tuned photoreactors to achieve maximal efficiency. This is a critical stumbling block unless the possibility for reactor design becomes available directly in the laboratories. In this work, customized laboratory photoreactors were developed with temperature stabilization and the ability to adapt different LED light sources of various wavelengths. We explore two important concepts for the design of photoreactors: reactors for performing multiple parallel experiments and reactors suitable for scale-up synthesis, allowing a rapid increase in the product amount. Reactors of the first type were efficiently made of metal using metal laser sintering, and reactors of the second type were successfully manufactured from plastic using fused filament fabrication. Practical evaluation has shown good accuracy of the temperature stabilization in the range typically required for organic synthesis for both types of reactors. Synthetic application of 3D printed reactors has shown good utility in test reactions—furan C–H arylation and thiol-yne coupling. The critical effect of temperature stabilization was established for the furan arylation reaction: heating of the reaction mixture may lead to the total vanishing of photochemical effect.
