Nano sensors and Nano fabrication — A World so Small, Made Big

What are Nanosensors

To understand what we are talking about further on, you need to understand what a nano sensor is, and how they came to be.

  • Types of organic molecules nearby
  • Pathogens and other Microorganisms
  • Change in PH, temperature, moisture and conductivity, pressure /flow, stress, position of nano particles, and forces
  • And more.
Subcategories that nano sensors fall under, as they observe different things.
  • Passive: Rely on factors in its environment to operate, and observations such as color, radiance, and opacity.

Why are they so Important?

How is something so small in our world, be so big in an emerging world of new technologies and society?

A great example of a device that uses nano sensors would be this nano-sized doughnut-shaped chip that attaches to the end of the catheter could improve the way doctors peek inside our circulatory systems.
  • For medical diagnostic purposes either as blood borne sensors or in lab-on-a-chip type devices
  • To monitor physical parameters such as temperature, displacement, and flow
  • As accelerometers in MEMS(micro-electromechanical system) devices like airbag sensors
  • To monitor plant signaling and metabolism to understand plant biology
  • To study neurotransmitters in the brain for understanding neurophysiology

How does something so small even work?

The components of a sensor system must include an analyte, sensor, transducer, and a detector, that allows for feedback from the detector to the sensor. The main goal behind the design of a sensor is to have accuracy, sensitivity and for it to be easily executed.

How do they create any type of nanotechnology to begin with?

The Problems and Challenges with Nanofabrication

Nano fabrication comes with many positives; for example, as the complexity of chain molecules is rearranged and reduced, a given material may become:

  • More flexible
  • More durable
  • Lighter-weight
  • Better able to resist temperature extremes
  • More resistant to environmental and other types of corrosion

How Can We Improve this Nanofabrication Process?
