 Nano sensors exist in the biological world as natural
receptors of outside simulation .
 Use of nano sensors
 sense of smell ,especially in animals in which it is
particularly strong,such as dogs
 Certain plants can detect sunlight
 Various fishes use nano sensors to detect small
vibrations in surrounding water.
 Magnetite,magnetic
nano particles of
specific morphology
are made by the
bacteria ,
magnetosperillum
magnetotacticum .
 There are several
bacteria like the
familiar lactobacillus
which can take up
metals ions added into
butter milk and reduce
them inside the cell and
make nano particles .
Fungi and virus are also known to make nano
particles .
