The panel is created using guide and text is placed using the set (handle.txt1,'String','10^{-3}') where txt1 is the tag of the text string that is being placed on the panel. How do I get substrings and superscripts on the panel screen. using Tex command '10^{-3}' doesn't work. I'm using Matlab 2017a.

You forgot to mention the type of the handle.txt1 object. It is not a "text string", but it might be an uicontrol('Style', 'text').

If you create an invisible axes and use text(), the LaTeX interpreter will work, in opposite to uicontrol's. If you really need an uicontrol, see: https://www.mathworks.com/matlabcentral/answers/269270-how-to-add-a-superscript-to-a-uicontrol
If the links solves your problem, note that it could be found by searching in the forum or in the net e.g. for "matlab subscript uicontrol".

I have a panel which i'm trying to place text to the left of a text box with the power of 10^-5 with the '-5' as a superscript(only with out the '^'). I'm also trying to use a subscript. I dont' see where you answer shows me how to do that. Right now i'm just placing the superscripts as a separate piece of text. see attached. Please be more specific.

I thought Jan's answer was clear. Replace your current uicontrol with an invisible axes. In that axes place some text with the text() function. text within an axes can be formatted with LaTeX markup which allows superscripts, subscripts and more.
Your only other options are to use a different type of uicontrol (not text or edit) that support html or to delve into Java, as per Jan's link.
