Abstract

In the present work biosensor was developed as an indicative of the time that the bacteria attacks the meat. The fabricated biosensor contained small inert particles in the nucleus, which served as indicative that bacteria were already consuming the biosensor, at the same time they were covered by a layer of PVA and another outer made of PLA or Cassava Starch. After 1 month of contact between the designed biosensors with meat, was determined as more effective that containing PLA in the outer cover since it allowed to observe the release of inert particles in less time as a visual indication that indeed the meat contained bacteria and that they consumed the outer layers of the sensor.

The process of RAMAN Microscopy in which the modification carried out the bacteria on the PLA could be observed conducted the characterization of the final product.
