El pasado lunes 2 de marzo, vino a nuestra clase el padre de Laura, Alfonso, y nos ense\u00f1\u00f3 c\u00f3mo investigaba la polic\u00eda cient\u00edfica.<\/p>\n
La unidad territorial es especialista en:<\/p>\n
Dactiloscopia<\/span><\/strong><\/p>\n Es el estudio de las huellas.<\/p>\n Las huellas est\u00e1n formadas por crestas y puntos caracter\u00edsticos que las hacen diferentes unas de las otras. El centro de la huella se llama n\u00facleo y los tri\u00e1ngulos inferiores se llaman deltas. Podemos tener 1 delta (monodelta), o 2 deltas (bideltas). Utilizamos diferentes tipos de pinceles (de fibra y de pelo de ardilla), as\u00ed como diferentes reactivos (magn\u00e9ticos, qu\u00edmicos y fluorescentes) para revelar las huellas. Las superficies ideales son las lisas y pulidas. Con 12 puntos caracter\u00edsticos encontrados en com\u00fan, podemos decir sin ning\u00fan tipo de duda a quien pertenece esa huella.<\/p>\n Documentoscopia<\/span><\/strong><\/p>\n Consiste en el estudio de los documentos y sus medidas de seguridad. Todos los documentos se elaboran en las f\u00e1bricas donde hacen los billetes. La mayor\u00eda de documentos tienen entre sus medidas de seguridad las tintas invisibles y las fibras fluorescentes, que se vuelven visibles con la luz ultravioleta. A trav\u00e9s del microscopio miramos la impresi\u00f3n y nos aseguramos de que no se haya hecho con una fotocopiadora o con un esc\u00e1ner.<\/p>\n Recogida de muestras para ADN<\/span><\/strong><\/p>\n El ADN es una mol\u00e9cula que lleva la informaci\u00f3n para crear las c\u00e9lulas que nos har\u00e1n diferentes del resto de personas. Podemos encontrar ADN en la piel, sangre, saliva, sudor, pelos, etc. Cuando extraemos el ADN de una persona, el resultado es como el c\u00f3digo de barras de un producto, encontramos l\u00edneas y n\u00fameros. El “BLUE STAR”, o reactivo para detectar sangre, se vuelve de color azul al entrar en contacto con el hierro que lleva la sangre.<\/p>\n Aparte de todo esto, tambi\u00e9n investigamos incendios, falsificaci\u00f3n de ropa y personas desaparecidas, como delitos m\u00e1s importantes, sin contar los homicidios.<\/p>\n Alfonso Gonz\u00e1lez, Afra, C\u00e8lia, Isolda, Carlota y Ariana.<\/p>\n <\/p>\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" El pasado lunes 2 de marzo, vino a nuestra clase el padre de Laura, Alfonso, y nos ense\u00f1\u00f3 c\u00f3mo investigaba la polic\u00eda cient\u00edfica.
