nanobiology

Nanobiology is an interdisciplinary field focused on biological processes and systems at the nanoscale and on using nanoscale tools to study, emulate, and manipulate life. It examines how biomolecules behave within the 1–100 nanometer range, how biological matter interacts with nanomaterials, and how nanoscale devices can probe biological phenomena.

Techniques from biology, chemistry, physics, and engineering are employed, including high-resolution imaging (atomic force microscopy, electron microscopy), single-molecule methods, nanopore sequencing, and super-resolution fluorescence. DNA nanotechnology and RNA origami provide programmable scaffolds for organizing biomolecules. Nanofabrication and self-assembly enable the creation of nanoscale sensors and delivery systems, while computational models help interpret interactions at the nanoscale.

Applications span nanomedicine (drug delivery, imaging, and theranostics), diagnostics, and biosensing. In fundamental research, nanobiology investigates how nanoscale context affects protein folding, gene regulation, membrane dynamics, and signaling. It also informs the design of biomimetic materials and synthetic biology constructs that operate at nanoscales.

Ethical and safety considerations include toxicity, environmental impact, privacy in diagnostics, and regulatory oversight. The field is closely related to nanotechnology and nanoscience, but centers on understanding and leveraging biology at nanoscale dimensions.
