• Breaking the final barrier: Room-temperature electrically powered nanolasers

  A breakthrough in nanolaser technology has been made by Arizona State University researchers. Electrically powered nano-scale lasers have been able to operate effectively only in cold temperatures. Researchers in the field have been striving to enable them to perform reliably at room temperature, a more

• A non-invasive intracellular 'thermometer' with fluorescent proteins has been created
  

  A team from the Institute of Photonic Sciences (ICFO) has developed a technique to measure internal cell temperatures without altering their metabolism. This finding could be useful when distinguishing healthy cells from cancerous ones, as well as learning more about cellular processes.Temperature c more

• Quartz crystal microbalances enable new microscale analytic technique
  

  A new chemical analysis technique developed by a research group at the National Institute of Standards and Technology (NIST) uses the shifting ultrasonic pitch of a small quartz crystal to test the purity of only a few micrograms of material. Since it works with samples close to a thousand times sma more

• Pressure Digestion for Sample Preparation
  

  What analyst does not wish for a universal method for processing all his or her samples? Pressure digestion represents just such a procedure for sample digestions and is therefore one of the standard sample preparation procedures currently employed in analytical chemistry for element quantification more

• Measurement of Nano particles and Proteins
  

  Colloid emulsions in their native environment require particle size determination in high concentration since there are concerns about changes in sample morphology upon dilution eg break up of aggregates. For proteins and other samples with very low concentration and for weakly scattering samples high sensitivity is required. New technologies offer both. more

• LOOXSTER® concentrates bacterial DNA
  

  Detection of the bacterial content of a specific sample, irrelevant from its source, is not as straightforward as it seems. In clinical microbiology laboratories, the gold standard method for the detection of pathogens in patients suspected of systemic infections is the blood culture. However, this technique is known to have many drawbacks especially with regard to patient's antibiotics treatment, low abundance and non-cultivable organisms. Moreover, it takes usually 3 to 5 days to obtain a result from blood culture which is too late to initiate proper antibiotic therapy. Amplification-based methods such as PCR allow results in a more rapid fashion. However, their sensitivity, to date, are no better, and sometimes worse, than culture-based methods. more
