Nano particles such as silver nanospheres, silver nanoprisms or lipid vesicles, can be produced at a high rate and with controlled precision (size) using continuous flow reactors. These are being fabricated and tested together with Engineering (Xunli Zhang).

In times of man-made global warming – and with it climate change – it is crucial to tackle general energy problems. Our efforts to contribute to this field is in the formation of silver nanoprisms, which efficiently absorb infrared light. These can be coated in a silica shell and covalently embedded in a PMMA matrix for coating of windows (J. Mater. Chem. C 2016). In this way we have shown that the Ag-NPs are able to block the IR light efficiently with sub-mm film thickness. This is a well-going collaboration with the group of Xunli Zhang in Engineering.

Our focus is on designing cheap flow-through reactors for the synthesis of nanoparticles (RSC Adv. 2014; J. Mater. Chem. C 2013), in particular silver nanospheres and nanoprisms, but they are also applicable to the fabrication of liposomes. We design the channels of the flow reactors according to best mixing of the different solutions and create a mould using 3D printing (New Biotechnology 2018). The reactor is then made using PDMS and either covering with a glass slide or adhesive tape. This allows to make a flow reactor in less than a day, at costs of less than £5.
