thanks Wilder - saw that article and thought it sounded like PULM's tech but didn't look into it. actually thought at the time that the only way it would be effective would be with PULM's tech or a copycat! good to know Langer is co-author and hope this new work is covered by PULM's patents.
the idea of introducing large, therapeutic biomolecules (including proteins) directly into lung was the primary reason for my initial enthusiasm and why I bought a bunch and continue to hold.... Also thought they'd have something in clinic by now after showing bioequivalence with generic bronchial dilator at one-tenth the dose. haven't been following them closely in months. damn stock looks to be heavily manipulated/suppressed.
maybe something good will happen in 2019...
