M = damping coefficient
C = mcantilever + mliquid
ζ = damping ratio
Caffeine↑⇒ Mass on the surface↑⇒ Oscillation frequency↓
⇒ frequency shift↑
MIP Coated crystal is very sensitive to the concentration of caffeine and
shows Very good linearity relationship
Effect of pH on the sensor response is optimum at pH 8 ⇒ Buffer solution
Characteristic of MOGS
1. Metal oxides possess electronic, chemical, and physical properties of high sensitivity to changes in their chemical environment.
2. The sensing properties of semiconductor metal oxide assures improved selectivity and stability
3. Their peculiar characteristics and size effects make them interesting for metal oxide gas sensors

of wrong diagnosis. and 0.8 % of the wrong diagnosis lead patients to death. In this reason, developing advanced diagnosis method is still required for fast and accurate diagnosis.
ECG (electrocardiography) is common method for diagnosing AMI. By using several diagnosis methods, we can get definite diagnosis for heart disease. however, The sensitivity of the ECG is about 65 %. It means that diag
Experimental
In fabrication of MWCNT based glucose enzyme sensor, MWCNTs were grown on the sensing chip of which detection is for obtaining the electrical signal of the input source counting the difference from the original value which is read on the reference electrode. 10ml glucose oxidase was prepared in a standard of 0.4mg/ml solution. On this CNT-grown area, place some of this glucose oxida
