Organic- or Inorganic-based Nanomaterials: Opportunities and Challenges in the Selection for Biomedicines

Since the inception of nanotechnology, several efforts have been dedicated to fabricating diverse nanodevices with exceptional performance. These innovative constructs have been applied in medicine due to their tailorable physicochemical properties (chemical composition, optical activity, spectra, and charge) and morphological attributes (size, shape, and surface area). Moreover, these versatile nanomedicines could promisingly offer better performance over the conventional therapeutic strategies. Broadly speaking, in terms of chemical composition, nanobiomaterials are classified into two predominant categories of organic and inorganic- based components. Despite their success and enormous versatile advancements in the past two decades, the significant progress towards clinical translation has been hampered by their corresponding intrinsic limitations. In this perspective, we give a brief overview of these organic- and inorganic-based materials, highlighting opportunities and challenges towards their utilization in medicine. Finally, we provide an interesting outlook on the lessons learned and look forward to further developing these materials, emphasizing their potential in clinical translation.
