NANO POLYMERS FORMATION Macro Micro Nano Å Å Molecules Monomers Small Bulk Material units or Micro Polymers Nano Bulk Material Polymers
Techniques Applied formation To Nano Polymers Top Down Approaches Nano Bottom Up Approaches Lysis of Bulky Materials:- Synthesis of Materials (Nano1. Chemolysis. (Use organic 1. Self Assembling. (Inter or Composites):- solvents ) Intra Molecular Nano polymers2. Thermolysis. (ΔG = ΔH – Interaction) TΔS) 2. Crystallization. ( Solid3. Radiation. (Break chemical and Liquid ) bonds, phenolic , 3. Precipitation. ( Liquid and polystyrene) Liquid recovery of salt4. Diffusion. (stirrer with high and metals) speed) 4. Sol-Gel. (NM + Organic5. Enzymolysis. (cellulase, Solvent + Gel) pectinase, ribulase..etc.) 5. Molecular6. Biodegradation. (bacteria, Interaction.(Ionic fungi, algae ..etc.) Interaction)
Model of Surface-to-volume Comparisons… Single Box Ratio 6 m2 2 3 1m 3 = 6 m /m Smaller Boxes Ratio 12 m2 3 = 12 m2/m3 1m Neglecting spaces between the smaller boxes, the volumes of the box on the left and the boxes on the right are the same but the surface area of the smaller boxes added together is much greater than the single box.
PROPERTIESStructural :- Platelets, Fibers, Spheroids, Linear, Branch, Network..etc.Physical & Chemical:- Like as Stiffness, Strength, Stability, etc. (2D,3D).Typical Structures are:• Linear (end-to-end, flexible) .• Branched(one end free, other attached to stalk polymer).• Network (similar to highly cross- linked structures,termosetting polymers).
Polymer has a MultidisciplinaryField of Science & Technology
Nano Based Polymers Types Chemical Synthetics - Polyglycolic acid (PGA) - Polylactic acid (PLA) - PGA-PLA - Polydioxanone (PDO) - Polycaprolactone - PGA-polycaprolactone - PLA-polycaprolactone - Polydioxanone-polycaprolactone Natural - Elastin - Gelatin collagen - Fibrillar collagen - Collagen blends - Fibrinogen - Heamoglobine

Outline Process of Nano-VectorNano polymer mostly can be very effective to be Designing aDrug as name “NANO VECTOR” by using of Nano Polymers andNano Materials in size nano range and also Applied for inducedtumor cells available in Critical Organs of Body such as Brain,Lung, Heart...etc. These vector designed a typical types, who aresearch to target site, that target site a specific receptor Presentedin outer cell membrane of the tumor cell receptor made bebecome Biomolecules it bind by various ways and released to NPinto tumor cells. Where It are do The tumor Cells Remove orDestroyed as may be possible without surgery Because SomeTumor Cell have arises to another Tumor Cell by Cell Cycling,here break Cell Cycling by This Nano Vector will as a processinginhabit of protein synthesis of tumor cell.
