(a)
Wich option is not related to langmuir blogget
precise control of the monolayer thickness,
homogeneous deposition of the monolayer over large areas
the possibility to make multilayer structures with varying layer composition
the size reflect the color

Qutum dot
Mesoporous
Nanocomposite
LB monolayer
Why nanocomposites are so multifuctional
high surface to volume ratio
increased ductility with no decrease of strength
Scratching resistance
Light transmission characteristics particle size dependent
All of the above
One lmitations present it in nanocomposites is?
Ductility
Have a matrix
Nanoclay modification of polymers such as polyamides, could reduce impact performance.
cant be used for intramuscular or subcutaneous applications
What are quatum dots
(a)
Quatum dots are?
semiconductors
complicated nano particle
hating quatum physics
good conductors
Quantum Confinement is
really heated quetum physics
Help me
the spatial confiment of electrons in one dimesion within the material
the spatial confinement of electron-hole pairs (excitons) in one or more dimensions within a material
Absorption and emission occur at specific wavelengths, which are related to QD size
True
False
Are quatum dots photostable?
Yes
No
i will know it later
The surface of QDs can be functionalized with affinity ligands: antibodies, peptides, or small-molecule drug inhibitors, to target specific types of cells for in vivo or in vitro
True
False
