The Regulatory Landscape of New Health Technologies and Nanotechnologies: The Role of Complexity of Nanosystems.

Herein we present the modern issue of new health technologies that emerge in Medicine and Therapeutics, with regard to their development, regulatory framework, approval, and post-approval monitoring. The European law and legislation distinguish the various subcategories of health technologies in medicinal products, medical devices, biotechnological products, advanced therapy medicinal products, and nanomedicinal products. Each of these categories presents its own distinctive characteristics, based on principles that regard the development technology and intended therapeutic use, and, as a result, is defined by a unique regulatory framework inside the European legislation environment. New health technologies are a key of twenty-first-century knowledge, science, and economy and a part of society growth and economic development, while at the same time they present significant challenges, mainly through matters that regard their safety, efficacy, and value for the public. In this environment, the concept of complexity of living and artificial systems arises, as part of their nature, but also as a perspective that will give answers regarding their dynamic behavior, evolution, and overall quality.
