\textsuperscript{87}Rb works fine in htlatex+biblatex combination. However,
if you have both subscript and superscript, htlatex will fail. You need to
generate MathML for mass/atomic numbers of the element, if not spacial
position will not be as you have expected. The following form works fine:

@article{ref, Title = {A {${}\sb{10}\sp{87}{\mathrm{Rb}}$} Bose
condensate}}

and will generate following output:

<math xmlns="http://www.w3.org/1998/Math/MathML"
display="inline">
<msubsup>
<mrow></mrow>
<mrow>
<mn>1</mn>
<mn>0</mn>
</mrow>
<mrow>
<mn>8</mn>
<mn>7</mn>
</mrow>
</msubsup>
<mstyle mathvariant="normal">
<mi>R</mi>
<mi>b</mi>
</mstyle>
[/itex]Bose condensate”.

Firefox renders correctly. In short, mzlatex+biblatex with modified input
will work OK.
