How big is a nanometre? How big is 1 cm in m? How big is 1 mm in m? 1 billionth m 0,000000001 m 1 hundredth m 0,01 m 1 thousendth m 0,001 m Give examples of how properties are changed in nano size Why is it a good idea to How can it happen, use drugs at nano size? when nano drugs are used in the body? Faster reaction Conductive Eksplosive Self-assembling drugs are wrapped in a sugar that the It can be targeted to specific body accepts. It will be transported exactly to where locations in the body the body needs it What kan nano silver be What is the purpose of used for? using nano silver? Fx socks and lunchboxes It prevents the growths of bacterias Are there any problems using nano drugs? Are there any problems How are nano drugs Why should nano be using nano silver? transported in the body? wrapped? That we do not know for sure, it might affect our health and environment It is wrapped as a 'Trojan horse', so that the body recognizes the packaging. Hidden inside is the drug. So the body feels safe, the drug seems harmless How is the nano drug wrapped? Tell what happened in the experiment with sugar, what did the experiment show about nano particle properties Tell what happened in the activity about encapsulation of paprika, what did the show about nano drugs? Paprika was meant to look like the drug. The wrapping Something similar to sugar It meant to show that the because thats a matter cells larger the surface, the faster inside oil was meant to look like sugar. Like a Trojan use. the reaction. horse. Tell what happened in the activity about drug transport What does selfassembling mean? Mention a molecule which is 1 nm long This means that the substances which meet each Glucose molecule which we The medicine self-assemble other self-assembles into a know from photosynthesis new compound C6H12O6 How big are the silver Mention examples of particles from the video? what nano technology are used for 20 nanometre Health Drugs Information Technology Energy Environment Mention some benefits of nanoscience Mention some risks of nanoscience Various subjects (in nano size) can be faster, more targeted, more effective Which tool do you need to see nano sizes? An elektronmicroskope We are not sure of the long term effects on our health and environment Mention examples of natural nano properties (from nature) DNA Lotus flower Galaxies ... How can one compare the relative sizes of nano sizes and other things we know? Fx Size relationship between nanoparticles and an apple, similar to the relationship between an apple and globe
