The pharmaceutical area can present some opportunities for mechanical engineers to develop a vast type of dosage forms particularly novel forms like nanoparticles. The classical education of mechanics needs some alterations to prepare appropriate education courses in this regard. In order to present some views about this issue, we collect some information around the importance of mechanical eng...
