Congratulations to Simon Shiu, Lewis Fraser (joint first authors) and Yifan Ding (former Final Year Project undergraduate student) for cover of July 2018 issue of Molecules, chosen as the cover from 338 articles in monthly issue.

Julian's research field is nucleic acid nanotechnology and applied molecular evolution for biomedical application. The Tanner lab brings together interdisciplinary experimental approaches at the interface of science, medicine and engineering to tackle major challenges in global health. His highly internationalised research team have developed radical new approaches for the point-of-care diagnosis of malaria, bridging nucleic acid evolution to 3D printing to clinical application. Recent accomplishments include the development of innovative designs of DNA nanotweezers and DNA origami, enabling sensing and detection of biomolecules driven by triggers of conformational change at the nanoscale. In more basic research, his team is exploring the biological functions of the fundamental yet enigmatic long-chain inorganic polyphosphates. Julian also has experience in educational research, with particular interest in how to build the best environment for research excellence and student achievement at the nexus between research, teaching and innovation.

Nucleic Acid Nanotechnology: We are investigating new methods to incorporate aptamers into functionalized DNA origami and into 3D printed millifluidic channels for point-of-care diagnostics.

Applied Molecular Evolution: We are developing new approaches in nucleic acid aptamer evolution and application in particular for diagnostics. We are using aptamers in new point-of-care diagnostic approaches for malaria and infertility and researching innovative technologies for nucleic acid evolution.

Inorganic Polyphosphate Function: Inorganic polyphosphate (polyP) is present in every cell in nature and consists of chains of tens or hundreds of orthophosphate residues linked by high-energy phospoanhydride bonds. We are investigating inorganic polyphosphate function in higher eukaryotes.
