Lens-Free
Automated Cell Counting System for
Diag**sis of Meningitis
French researchers from Gre**ble Alpes University and Aix-Marseille University have developed an
Automated Lens-Free microscopy technique for
Counting and telling apart red and white blood cells withing cerebrospinal fluid. Cerebrospinal fluid, gathered through a spinal tap, should be clear and have few, if any, blood cells within it. Patients with meningitis, due to inflammation and disruption of the membranes enveloping the brain, have white blood cells seeping into the cerebrospinal fluid (>10/خ¼L). Doing a
Cell count on a sample of the fluid goes a long way toward a diag**sis.
The new microscopy
System takes less than 50آ*خ¼L of cerebrospinal fluid and automatically counts the cells within. Though manual
Counting using a traditional microscope is quite effective, the small size and
Automated nature of the new
System allows it to be implemented for point-of-care diag**stics.
The lenseless
System consists of a CMOS image sensor on top of which the sample is placed. A light plane wave illuminates the sample, producing a holographic image that the sensor captures. This allows the sensor to see the sample and a computer program is then used to interpret the image into a
Cell count.
