Google Glass to monitor plant health

‘Okay Glass, image a leaf’

Scientists in the US have developed their very own pair of rose-tinted spectacles by adapting Google Glass to measure the chlorophyll concentration of leaves.

Aydogan Ozcan and his research group at the University of California are passionate about creating new technologies through innovative, photonic methods and are well acquainted with the possibilities of wearable technology in scientific research. Chlorophyll concentration is a handy metric for monitoring plant health and the system devised by Ozcan’s team combines Google Glass with a custom made leaf holder and bespoke software to determine just that.

Silver lining for paper Ebola test

Ebola, yellow fever and dengue can be tested for in one go

Researchers in the US have developed a silver nanoparticle-based paper test to simultaneously detect dengue, yellow fever and Ebola. This could provide a cheap and reliable diagnosis for all three diseases, that’s as quick as a home pregnancy test.

The Ebola epidemic in West Africa underscores an urgent need for rapid diagnostics; quick identification and patient isolation can benefit the sick and the healthy. However, dengue, yellow fever and Ebola all initially manifest as a fever and headache, so are easily mixed up.

Introducing Editorial Board Member Xudong Fan

We are delighted to welcome Xudong (Sherman) Fan to the Lab on a Chip Editorial Board.

Dr Fan is currently a Professor in the Department of Biomedical Engineering at the University of Michigan.

Having completed his B.S and M.S at Peking University, Xudong moved to the USA to complete his PhD at the University of Oregon in the Oregon Center for Optics. From 2000 to 2004, Xudong worked at Research Corporate Lab at 3M Company. In 2004 he took up a position as an Assistant Professor at the University of Missouri where he became a member of Christopher S. Bond Life Sciences Center and the International Center for Nano/Micro Systems and Nanotechnology. In 2010 Xudong moved to the University of Michigan where he is currently a Professor of Biomedical Engineering, a member of Michigan Center for Integrative Research in Critical Care and Wireless Integrated Microsensing and Systems.

My Research Goal:
“My research goal is to use the state-of-the-art photonics, nanotechnology, microfluidics, and other engineering tools to detect and analyse bio/chemical species in both liquid and gas phases.”
Professor Xudong (Sherman) Fan, Lab on a Chip Editorial Board Member

Research in The Fan Lab focuses on the development of novel bio/chemical sensor platforms for analytes in either liquid or gas phase using optofluidic technology and multi-dimensional micro-gas chromatography technology. The groups most recent publication in Lab on a Chip ‘Optofluidic lasers with a single molecular layer of gain’ was added to our Lab on a Chip 2014 HOT Articles collection as it received particularly high scores during peer review.

Last year Xudong received a Departmental Award for Outstanding Accomplishment and become a fellow of Optical Society of America. Congratulations Xudong!

Chip-on-a-cell

Scientists in Spain have flipped the cell-on-a-chip concept to bring us a chip-on-a-cell

Field emission scanning electron microscopy images of a barcode attached to the zona pellucida of a mouse embryo

Jose Antonio Plaza of the Institute of Microelectronics Barcelona and colleagues affixed polysilicon chips, which act as barcodes, onto the outer surface of the zona pellucida, a membrane that surrounds immature egg cells and embryos. Although silicon nanowires penetrated the membrane to attach the chip, they did not interfere with embryo development in tests on mouse embryos.

A chemical time capsule

Inspired by tree rings, scientists have designed a sensing device that records chemical information over time as spatial patterns.

The transformation of time-varying signals into spatially-varying signals is fundamental for recording temporal information. For trees, growth rings that form throughout their lifetime provide a historical record of their growth conditions. Now, a team led by Sindy Tang at Stanford University, US, have designed a time capsule to record information about the occurrence of chemical events.

2014 Pioneers of Miniaturisation Lectureship Winner

Dr. Sangeeta N. Bhatia is winner of  the 2014 Corning Inc./Lab on a Chip Pioneers of Miniaturisation Lectureship

The 9th ‘Pioneers of Ministurisation‘ Lectureship, is for extraordinary or outstanding contributions to the understanding or development of miniaturised systems and will be presented to Dr Bhatia at the µTAS 2014 Conference in San Antonio, Texas in October. Dr Bhatia will receive a certificate, $5000 and will give a short lecture at the µTAS Conference, later this year.

About the winner

Dr Bhatia conducts research at the intersection of engineering, medicine, and biology to develop novel platforms for understanding, diagnosing, and treating human disease. Her ‘tiny technologies’ interface living cells with synthetic systems, enabling new applications in tissue regeneration, stem cell differentiation, medical diagnostics and drug delivery. She and her colleagues were the first to demonstrate that microfabrication technologies used in semiconductor manufacturing could be used to organize cells of different types to produce a tissue with emergent properties. Dr. Bhatia’s findings have produced high-throughput-capable human microlivers, which model human drug metabolism, drug-induced liver disease, and interaction with human pathogens. Her group also develops nanoparticles and nanoporous materials that can be designed to assemble and communicate to diagnose and treat a variety of diseases, including cancer.

Dr. Bhatia co-authored the first undergraduate textbook on tissue engineering and has published more than 150 manuscripts, that have been cited over 13,500 times. She and her 150+ trainees have contributed to more than 40 issued or pending patents and launched 9 biotechnology companies with close to 100 products. She is a frequent advisor to governmental organizations and consults widely for academia and industry.

Dr. Bhatia holds a B.S. from Brown University; an M.S. in mechanical engineering from MIT; a Ph.D. in biomedical engineering from MIT; and an M.D. from Harvard Medical School and currently she directs the Laboratory for Multiscale Regenerative Technologies at MIT. She is a Howard Hughes Medical Institute Investigator and the John J. and Dorothy Wilson Professor of Health Sciences and Technology and Electrical Engineering and Computer Science at MIT. She is a member of the Institute for Medical Engineering and Science and the Koch Institute for Integrative Cancer Research at MIT, a senior member of the Broad Institute, and a biomedical engineer at Brigham & Women’s Hospital. Dr. Bhatia is an elected Fellow of the Massachusetts Academy of Sciences, Biomedical Engineering Society, American Institute for Medical and Biological Engineering, and the American Society for Clinical Investigation.

We would like to congratulate Dr Bhatia on this achievement!

The 2013 Pioneers of Miniaturisation Lectureship was awarded to Shuichi Takayama, University of Michigan.
