Would you know why the spacing between column "ssDNA8" and "dsDNA2" on line 2 looks more narrow than between "ssDNA1" and "dsDNA0", "ssDNA5" and "dsDNA5" ?
\begin{table}
\centering
\begin{tabular}{@{}l@{\hspace*{0.1cm}}c@{\hspace*{0.4cm}}c@{\hspace*
{0.6cm}}c@{\hspace*{0.4cm}}c@{\hspace*{0.6cm}}c@{\hspace*{0.4cm}}c@{}}
\toprule
&\multicolumn{1}{c}{ssDNA8} & {dsDNA2} & {ssDNA1} & {dsDNA0} & {ssDNA5} &
{dsDNA5} \\
\hline
\\[-1em]
A$_{\text{1}}$&\multicolumn{1}{c}{1240 ± 80} & {1540 ± 100} & {4420 ± 30} &
{8960 ± 30} & {1110 ± 40} & {8880 ± 20} \\
\bottomrule
\hline
\end{tabular}
\label{table1}
\end{table}
I would like to have a small and identical spacing in line 2, between columns "ssDNA8" and "dsDNA2", "ssDNA1" and "dsDNA0", "ssDNA5" and "dsDNA5" and a larger and identical spacing between columns "dsDNA2"and "ssDNA1", "dsDNA0"and "ssDNA5".

Something along the following lines may be what you're looking for. I suggest that if you want to vary the amounts of intercolumn whitespace, you should make it really obvious. 4mm vs 6mm may simply not be enough variation; consider 3mm and 8mm, say, instead.
