**3. Advantages of nanobiotechnology**

Nanoformulation based on oral and topical drug delivery in biotechnology can stimulate molecular imaging for brain tissue engineering and drug delivery through blood brain barrier, Improvement of CNS directed neuroprotection or regeneration, drug uptake assistance, showing fewer side-effects compared to conventional molecules, more active therapeutically in treating brain tumors, Successful biodistribution, High bioavailability, DNA and RNA molecules provide high affinity and binding on specific target site, devoid of enzymatic degradation enriches lymphatic
