Concatenate Cells In Columns & Change Part Of Font

I need for it do perform the same action on multiple rows/ cells of data. What adjustment to the code needs to be performed to do so?

Sub fconcat()
Range("C1").Value = Range("A1").Value & Range("B1").Value
For i = 1 To Range("A1").Characters.Count
Range("C1").Characters(i, 1).Font.Name = Range("A1").Characters(i, 1).Font.Name
Next
For i = 1 To Range("B1").Characters.Count
Range("C1").Characters(Range("A1").Characters.Count + i, 1).Font.Name = Range("B1").Characters(i, 1).Font.Name
Next
End Sub
