By interconnecting nanomachines and forming nanonetworks, the capacities of single
nanomachines are expected to be enhanced, as the ensuing information exchange will allow them
to cooperate towards a common goal. Nowadays, systems normally use electromagnetic signals to
encode, send and receive information, however, in a novel communication paradigm, molecular
transceivers, channel models or protocols use molecules. This article presents the current developments
in nanomachines along with their future architecture to better understand nanonetwork
scenarios in biomedical applications. Furthermore, to highlight the communication needs between
nanomachines, two applications for nanonetworks are also presented: i) a new networking paradigm,
called the Internet of NanoThings, that allows nanoscale devices to interconnect with existing
communication networks, and ii) Molecular Communication, where the propagation of chemical
compounds like drug particles, carry out the information exchange.
