Bringing artificial enzymes closer to nature

31-Aug-2016 - Scientists at the University of Basel, ETH Zurich in Basel, and NCCR Molecular Systems Engineering have developed an artificial metalloenzyme that catalyses a reaction inside of cells without equivalent in nature. This could be a prime example for creating new non-natural metabolic pathways ...

Thermochemical nanolithography now allows multiple chemicals on a chip

18-Dec-2009 - Scientists at Georgia Tech have developed a nanolithographic technique that can produce high-resolution patterns of at least three different chemicals on a single chip at writing speeds of up to one millimeter per second. The chemical nanopatterns can be tailor-designed with any desired shape and ...

Biosensing nanodevice to revolutionize health screenings

26-Mar-2008 - One day soon a biosensing nanodevice developed by Arizona State University researcher Wayne Frasch may eliminate long lines at airport security checkpoints and revolutionize health screenings for diseases like anthrax, cancer and antibiotic resistant Staphylococcus aureus (MRSA). Even more ...

Soft microlenses as biosensors: change in focal distance signals presence of analyte molecules

14-Feb-2006 - In the future, microscale gel lenses could play a role as biosensors for analysis and diagnostics. Researchers at the Georgia Institute of Technology have developed microlenses that react by changing their focal distance when a target substance is present. Gels consist of a three-dimensional ...
