  In this paper, we investigate information-theoretic scaling laws, independent
from communication strategies, for point-to-point molecular communication,
where it sends/receives information-encoded molecules between nanomachines.
Since the Shannon capacity for this is still an open problem, we first derive
an asymptotic order in a single coordinate, i.e., i) scaling time with constant
number of molecules $m$ and ii) scaling molecules with constant time $t$. For a
single coordinate case, we show that the asymptotic scaling is logarithmic in
either coordinate, i.e., $\Theta(\log t)$ and $\Theta(\log m)$, respectively.
We also study asymptotic behavior of scaling in both time and molecules and
show that, if molecules and time are proportional to each other, then the
asymptotic scaling is linear, i.e., $\Theta(t)=\Theta(m)$.
