Nanotechnology: the future is now [Taiwan R&D initiatives]

As a small economy that has built its future on manufacturing excellence, Taiwan has a big stake in nanotechnology. On the one hand, our manufacturing strength makes nanotechnology a unique opportunity. On the other, it also makes nanotechnology the one R&D battle we can least afford to lose. To come out ahead takes coherent planning and disciplined actions and, above all, the ability to marry nanotechnology's creative power to the dynamics of the marketplace. Such will be the challenges facing Taiwan's National Nanotechnology Program and its central R&D force-ITRI. For us, the future is literally now.     

Nanotechnology-Based CAR-T Strategies for Improving Efficacy and Safety of Tumor Immunotherapy

Therapeutic responses to chimeric antigen receptor (CAR) T cell therapy in patients with limited treatment options have been appealing in several clinical trials. However, the efficacy of CAR-T therapy has been challenged by several obstacles when treating patients with solid tumors, such as severe toxicities, restricted access to tumor sites, suboptimal therapeutic persistence, and manufacturing issues. Nanotechnology has the advantages of protecting CAR-T cells from being suppressed by tumor microenvironment (TME) and favorably adapting immune-modulating drugs’ pharmacokinetics by modifying their spatiotemporal release profiles. Loaded with nanoparticles and packed onto CAR-T cells, immune-modulating drugs can be delivered to the tumor site and lymph node more efficiently, stimulating the expansion and activity of CAR-T cells. To protect normal tissues from the nonspecific toxicity of the activated CAR-T cells, formulations are optimized toward tumor targeting delivery of nanotechnology. This review summarizes the nanotechnology strategies to improve the safety and efficacy of CAR-T therapy. In addition, the unsolved problems existing in the clinical application of CAR-T therapy are focused on, where study and exploration by the way of nanotechnology is needed.     

Tiny ethics for big challenges: calling for an ethics of nanoscale science and technology

This article suggests that as we consider the social and ethical dimensions of nanotechnology development; inclusion of analyses of the role of human cognition is essential. Cognition is formed from sensory-motor experiences, beliefs, ambitions, and ideas; scientific research and technological development are expressive of these elements of cognition, ultimately in the technological goods we use and consume. By understanding the role of imagination, which is imbedded in the cognitive process, we will be better equipped to glean the meaning of the development of nanotechnology and to direct that development toward conscientious and humanitarian ends.
