Lawrence Livermore Microbial Detection Array (LLMDA)
A research team from the Lawrence Livermore National Laboratory has developed a miniature biosensor that is capable of identifying microbes in a sample within 24 hours. The original one-inch wide, 3-inch long Lawrence Livermore Microbial Detection Array (LLMDA) can identify approximately 2,000 viruses and 900 bacteria. However, a more advanced version currently under development will be able to detect about 5,700 viruses, thousands of bacteria and fungi as well as about 75 protozoa.

Frederick Balagaddé, another scientist at the Lawrence Livermore National Laboratory, has developed a microfluidics-based detection chip which functions to not only detect HIV, but also determine viral load in patients.
George Whitesides’s Postage-Sized Laboratory
Made only of paper and a water-repellant polymer, this biosensor can be used for detecting various biological compounds that can signify health or disease.
