What is Biophysics?
Biophysics is an interdisciplinary science that applies the principles and methods of
physics to understand biological systems. It explores the physical properties of biomolecules, cells, and tissues, and how they interact with their environment.
How Does Nanotechnology Intersect with Biophysics?
Nanotechnology involves manipulating matter at the atomic and molecular scale, typically below 100 nanometers. In the context of biophysics, it enables the study and manipulation of biological materials at a nanoscale, offering insights into their structure, dynamics, and function.
Drug Delivery: Nanoparticles can be engineered to deliver drugs precisely to targeted tissues, improving the efficacy and reducing side effects.
Imaging: Nanoscale imaging techniques, such as quantum dots and nanoscale MRI, enhance the resolution and sensitivity of biological imaging.
Biosensors: Nanosensors can detect biological molecules at extremely low concentrations, facilitating early diagnosis of diseases.
Tissue Engineering: Nanomaterials can be used to create scaffolds that mimic the extracellular matrix, promoting tissue regeneration.
Molecular Motors: Understanding and harnessing the function of nanoscale biological motors can lead to the development of nanoscale machines.
Atomic Force Microscopy (AFM): Allows for the imaging and manipulation of individual molecules and complexes.
Cryo-Electron Microscopy (Cryo-EM): Provides high-resolution images of biological specimens in their native state.
Single-Molecule Fluorescence: Enables the observation of individual molecules in real-time, providing insights into their behavior and interactions.
Nanopore Sequencing: A technique for sequencing DNA by passing it through a nanoscale pore, offering a fast and accurate method of genomic analysis.
Nanoscale Spectroscopy: Techniques such as Raman spectroscopy can provide detailed information about molecular composition and dynamics at the nanoscale.
