This chapter describes the evolution of polymer chemistry in the last decades.
Orientation towards chemistry of life, getting some macromolecular compounds with
curative properties and involvement in nanobiotechnology were the main decisions that
preserve the importance of this field. On the other hand, weak points of the polymers
have been identified which often represent a barrier to full acceptance of polymers in
medical practice.
Overcoming these barriers and integrating polymers in medical practice is conditioned
by adopting an interdisciplinary atittude, by abandonment of low-performing
methodology and by opening toward innovation and originality.
Keywords: Magic bullet, macromolecular chemistry, polydispersity,
biodegradable polymers, non-viral gene delivery, rheumatoid arthritis.
