| Summary: | Nowadays, biological detection is needed in some industry. Some of detection <br />
<br />
method already done but in this research we use sensor based surface plasmon <br />
<br />
resonance which have a high sensitivity and one of free label method. Detection <br />
<br />
without specific tag or color used to get high sensitivity measurement of analyte <br />
<br />
or biomolecules. One way to exited SPR is Total Internal Reflection (TIR) in <br />
<br />
boundary of dielectric and metal from fiber optic. Therefore, in this research <br />
<br />
fabrication and simulation using Comsol Multiphysics 5.3 of tapered fiber was <br />
<br />
done. Simulation was done to know the effect of electromagnetic field of sensor. <br />
<br />
Krestchmann method and tapered fiber was done with some variation such as type <br />
<br />
of metal, thickness of metal, angle of incidence and also wavelength. The tapered <br />
<br />
fiber that generated have a 9 degree tilt by tapering rig and can be used to <br />
<br />
biomolecule detection with an amount dip friction of porcine is 34,12 nm and <br />
<br />
12,97 nm bovine. Besides that, from the simulation of sensor which was produced <br />
<br />
known that have a 2,3891 sensitivity of sensor. |
