Malaria could be tested early by cheap, portable device
A device that measures electrical properties of red blood cells is able to detect if they are infected with malaria in the early stages. Theresearchers hope their findings will lead to a portable and low-cost, yet highly sensitive device that can diagnose malaria on the spot using just a drop of blood.
Anantha Chandrakasan and colleaguesfrom the Massachusetts Institute of Technology (MIT) write about how they developed and tested their experimental microfluidic device in the journal Lab Chip. The device spreads the drop of blood onan electrode that can count individual cells as they stream past, and it can also take very accurate readings of their impedance or electrical resistance. In previous studies, the team had alreadyestablished that diseases like malaria alter the electrical properties of red blood cells.
Chandrakasan, who specializes in developing low-power electronic devices, told the press:
"Ultimately the goalwould be to create a postage stamp-sized device with integrated electronics that can detect if a person has malaria and at what stage."

La mayoría de los nuevos artículos y publicaciones médicas se enfocan más en el modelo clínico(curativo) y a la creación de nuevos fármacos capaces de combatir con las enfermedades más tenaces. Lo cual es de suma importancia y necesidad en la medicina de hoy en día, Sin embargo, elegí este articuloel cual se enfoca mas en el modelo preventivo y de diagnostico porque le permite a la gente saber si esta contagiada con malaria y en qué etapa, permitiendo la rápida atención medica que a su vezpreviene complicaciones a futuro.
Si llevamos esta idea a nuestro país (Venezuela) sería de gran aprovechamiento tener estos equipos en los lugares donde hay mayores casos de malaria (Bolívar,...
