Gold nanoparticle solution: An alternative tool for discriminating between pleural transudate and exudates

Sir, the present advent in nanomedicine leads to the newdevelopment and introduction of many new nanodiagnostictools. The naked eye system nanodiagnosis is the new hope forserving as point of care analysis. The application in body fluidanalysis in laboratory medicine is very interesting. The goodexample is the application of gold nanoparticle solution forrapid detection of cerebrospinal cryptococcosis (1).
