“…Scaling exponents are commonly referred to as ‘subdiffusion’, whereas values are termed ‘superdiffusion’. Subdiffusion with scaling exponents has been observed very frequently, at least on short and intermediate time scales, for tracer particles in complex media, e.g., in equilibrated biomimetic crowded fluids [ 6 , 7 , 8 , 9 , 10 ], in the cytoplasm [ 6 , 11 , 12 , 13 , 14 , 15 ] and in the nucleoplasm [ 11 , 16 , 17 , 18 ] of living cells, as well as on biomembranes [ 19 , 20 , 21 , 22 ]; see also [ 23 , 24 ] for extensive reviews.…”
