Nanotechnology Flashcards
What is an advantage of a novel delivery system?
Target the drug to the diseased area, lower the side effects and enhance the efficacy
What cancer therapies have been succesfully formualted using nanomaterials/
Paclitaxel, Doxorubicin, 5-fluorouracil. dexamethasone
What are the common bases of nanotech?
PLGA and PLA
What is the difference between passive targeting and active targeting?
Passive: Tendency of unmodified delvier ysstem to gather in specific tissues
Active: utlilizes a ligand on the surface of the novel deliver system
What are the 6 drug delivery carriers?
Micelles, Vesicles, Multifunctional dendritic polymers, nanospheres, nanocapsules, liquid crystals
What is the approxiamte size of a liposome?
100nm
What are the classes of polymer therapeutics?
What are the classes of lipid based delivery systems/
What are the polymer drug/protein conjugates?
What are polyplexes?
What are dendrimers?
3 components which include initiator core
Interior layers composed of repeating units attached to interior core
Exterior attached to the outermost interior layers
What is a micelle?
Self assembly of amphiphilic polymers or surfactants
CMC*
What is the CMC point we attempt to reach?
What is a SLN?
Solid lipid nanoparticle
Size 50-1000nm
Matrix is solid lipids or mixtures of lipids
Review the next slide about the different types of SLN
What are nanoemulsion?
Lipid monolayer enclosing a liquid lipid core ***Liquid is key
How do you form nanoemulsions or SLN?
High pressure homogenization
What are liposomes?
These have 2 layers like a cell where the core ncloses water or aqueous soln
What are nanocapsules?
What are nanospheres?
What are polymeric nanoparticles?
Solid, colloidal particles consisting of artificial or natural polymers where the drug is dissolved entrapped in a encapsulated polymer
What is a key characteristic of a polymer?
Must be biocompatible and degredable and nontoxic
What is PLGA?
Both biocompatible and biodegradable
What is the global market of nanoparticles?
83.4 billion in 202 to 123.6 billion in 2025
