DNA Nanomotor Rotates Autonomously
A scientist at the University of York has succeeded in conducting the first tests on a tiny rotating machine that is made entirely from DNA. The technology has potential applications in molecular processing, DNA computing, biomedical sensing and photonics.
In living things, DNA stores genetic information. However, it is also possible to use chemically synthesized DNA molecules to build artificial structures and devices that are so small they could fit thousands of times across the diameter of a human hair.
Most DNA nanomotors move in straight lines and the few DNA machines that do rotate are generally unable to do so independently.
Dr Katherine Dunn, from the University of York’s Department of Electronic Engineering has now developed a DNA nanomotor that is designed to rotate autonomously. “Naturally occurring rotary molecular machines play extremely important roles in living things
and it is now possible to use DNA to make synthetic rotary motors that operate without external intervention. This work represents a significant advance and the motor has a number of exciting potential applications.”
The research* was funded by the University of York’s Research Innovation Office and written by Dr Katherine Dunn, with co-authors from the Departments of Physics, Biology and Electronic Engineering. The University of York filed a patent application for the technology and commercial partners are now being sought to develop it further. Any interested parties are invited to get in touch, visit

BioTek Awarded 2016 Governor’s Excellence in Worksite Wellness Award
BioTek Instruments was once again awarded the 2016 Governor’s Excellence in Worksite Wellness Award. This award recognises Vermont companies that promote health and wellness in the workplace for the betterment of their employees. BioTek’s Vice President of Human Resources, Kathy Gendron, was recognised by the Governor’s Council on Physical Fitness and Sports as an outstanding individual in the leadership of BioTek’s wellness program.
BioTek’s wellness program includes a variety of activities and initiatives including onsite fitness and educational classes, subsidised gym memberships and smoking cessation assistance. The Company also
declared its grounds a smoke-free campus as of January 2017.
The Company’s President and CEO, Briar Alpert, noted: “Receiving this award again is a real honour. Our people and our culture are really the backbone of our company and we know that healthy employees are happy employees. So taking care of our employees and giving them access to affordable healthcare and to educational materials is a priority for BioTek.”

Manchester Physicists Receive Prestigious Honours
achievements in original research and Professor Guinea joins two other Manchester University members of the NAS; Professor Sir Andre Geim, Professor of Condensed Matter Physics and Professor Sir Salvador Moncada, Institute Director of Cancer Sciences.
Also during early May, Dr Radha Boya was one of five scientists honoured with the L’Oreal-UNESCO Fellowship for Women in Science. The programme recognises the achievements of exceptional female scientists across the globe and awards them with fellowships to help further their research.
Professor Francisco Guinea, from the School of Physics and Astronomy at the University of Manchester has been elected Foreign Associate to the US National Academy of Sciences (NAS). Professor Guinea is one of 21 new foreign associates recognised for their distinguished and continuing achievements in original research.
Professor Guinea’s field of expertise lies in theoretical condensed matter physics. He is active in developing models for the description of the properties of novel materials such as graphene. He is also a Senior Research Professor at INDEA Nanoscience in Madrid. Members are elected to the NAS in recognition of their continuing
At an awards ceremony in London on Thursday 4 May Dr Boya said: “I owe my success to the women in my life.” Dr Boya is a Leverhulme early career fellow and Dame Kathleen Ollerenshaw fellow at The University of Manchester, where she is establishing a new research group exploring the fundamentals and applications of atomic scale nanocapillaries.
After completing her PhD in 2012 in JNCASR, India with recognition of ‘Best Thesis’, she has been funded through a series of highly competitive and prestigious fellowships, including Indo-US pre- and postdoctoral, Marie Curie international fellowships. She has published 37 papers and holds three patents.
