Transcripts - Nanotechnology in biological applications

  • 1. Width = 0.1 mm  = 100 micrometers   BY SREEREMYA.S  M.phil Single Hair 1 nanometer = one billionth (10-9) meter
  • 2. By 2020, $1trillion worth devices will be nano-engineered Nanotechnology is already begining to revolutionise the electronics industry, computing, medicine, cosmetics, food, energy generation and the military sectors.
  • 3.  Life style  Health  Technology  Environment
  • 4.  Textile  Odorless, Stain resistant, flame retardant, wrinkle resistance, moisture management, antimicrobial qualities, IR absorption, UV protection, and soil release properties, Ecological etc  Medical textile (neurodermatitis), Wound dressing  Antimicrobial coating  High washing fastness, self cleaning  Environmental protection – smoke, volcanic erruption, exhaust gases, unburned carbon repellant
  • 5.  Shelter  bricks, cement, steel, coatings, paints,sensors  Nano SiO2 – to improve mechanical strength  Addition of nanofibres (say CNT) improve compressive and flexural strength  Crack free concrete – healing polymers  High corrosion resistant steel  Coatings or Paints - Anti fraffiti, thermal control, energy sawing, antireflection  When exposed to UV light – TiO2 nanoparticles in paint breakdown organic and inorganic pollutants that wash off with the rain water  Decompose air pollution particles like formaldehyde  Sensors to identify early concrete properties such as moisture, temperature, relative humidity – piezoceramic devices  Sensor to monitor health of the construction
  • 6.  Agriculture and food (nanofood consortium in 2006)  Molecular treatment of diseases in plants, rapid disease detection, enhancing the ability of plants to absorb nutrient - nanofertilizers  Smart sensors and smart delivery systems to combat viruses and other crop pathogens  Nanostructured catalyst to enhance efficiency of pesticides and herbicides  To clean ground water  Sensors to test quality of packed food (micobiological and biochemical changes)  Improve materials for food packing such as permeation behaviour of foils, increasing barrier properties (mechanical, chemical, thermal and microbial), heat resistance properties, developing antimicrobial and antifungal surfaces  Artificial food for health concern - low fat, diabetic, etc
  • 7.  Transportation: (safe, durable, economical and sustainable facility for movement)  Hydrophobic road surfaces (ZnO2)  Skid resistant and less abrasive tyres ( SiC- elastomer)  Better signage ( nanophosphors)  Auto-luminescent infrastructure surfaces to guide traffic at night  Reducing energy consumption  Limiting pollution (NOx pollution)  Traffic monitoring sensors  Target - Cost effective and economical
  • 8.  Cardiology  Opthalmology  Endocrinology  Oncology  Pulmology  Immunology  Genedelivery  Brain targeting  Tumor targeting  Oral vaccination
  • 9.  Increased Surface to Volume ratio results in  Increased solubility and absorption rate of drug  Increased rate of dissolution  Increased oral bioavailability  Promises precision administration  Smaller dosages – reduced side effects  Improved patient compliance  Decreased patient to patient variability in dosages
  • 10.  Implants – Seeds, hip joints, stents, nail, dental implants (Permanent) – Catheters, needles (temporary) Seed : Iodine 125 is loaded: Gold wire is kept for X ray visibility all enclosed in the ceramic capsule of 4.5mm x 0.08mm
  • 11. In todays scenario there, many other scientific inovations are carried out in the field of nano technology
