Resumen:

In this paper, a calibrated using a mathematical model for Radiometry Photothermal technique Infrared, considering their use in biomedical applications instrument, experimental technique consists of a medium-power laser, which develops switches by an electro-optical modulator, subsequently incident on the sample, the radiation is collected and focused onto an infrared detector, the signal of interest on the sample is obtained by using a look-in amplifier, thereby obtaining the amplitude and phase of the modulated signal, data are collected in a database by an embedded system using serial communication. The data is analyzed to determine sample parameters in Ag nanoparticles of 10 to 30 nm. on diameter average were obtained by chemical reduction of AgNO3, the solution containing 0.025 mu m. Silver nitrate in 250 mL of deionized water was heated to 100 degrees C and stirred mechanically. A citrate solution of 1, 0.5, 0.25, 0.125 and 0.062 % in water was added.
