Surgical nano-biothread made from cellulose fiber
A method of making a surgical biothread from natural cellulose fiber is provided. The method includes making nanoscale cellulose using acid hydrolysis and pyrolysis of a mixture of palm tree stems and banana flower bracts; mixing the nanoscale cellulose with a plasticizer to obtain a nanoscale polymer; and casting the nanoscale polymer using a syringe and needle to obtain the biothread.
1. A method of making a nanobiothread, comprising:
a. providing a mixture of waste palm tree stems and waste banana flower bracts;
b. acid hydrolyzing the mixture;
c. pyrolyzing the mixture to obtain a nanoscale cellulose blend;
d. mixing the nanoscale cellulose blend with a plasticizer to obtain a nanoscale polymer; and
e. casting the nanoscale polymer using a syringe and needle to obtain the nanobiothread.
2. The method of claim 1 , further comprising washing the mixture and bleaching the mixture prior to acid hydrolyzing the mixture.
3. The method of claim 2 , wherein washing the mixture comprises soaking the mixture in water for about 4 hours.
4. The method of claim 2 , wherein bleaching the mixture comprises soaking the mixture in sodium hypochlorite for about 4 hours.
5. The method of claim 1 , wherein acid hydrolyzing the mixture comprises adding about 75% to about 80% sulphuric acid to the mixture.
6. The method of claim 1 , wherein pyrolyzing the mixture is conducted in an oven at about 135° C. for about 3 hours.
7. The method of claim 1 , wherein mixing the nanoscale cellulose blend with a plasticizer comprises mixing about 48% of the nanoscale cellulose blend with about 5% v/v polyvinyl chloride, about 8% v/v pure cellulose and about 8% v/v starch.
8. The method of claim 7 , further comprising mixing the nanoscale cellulose blend with one or more dyes selected from the group consisting of 5% v/v orange and mango peel dye, 5% v/v turmeric organic dye, and a combination thereof.
9. The method of claim 7 , further comprising mixing the nanoscale cellulose blend with one or more components selected from the group consisting of 4% v/v aloe vera gel, 4% v/v flaxseed gel, 4% v/v arabica gel, 5% v/v waste cooking oil-based glycerin, and a combination thereof.
10. The method of claim 7 , further comprising mixing the nanoscale cellulose blend with 4% v/v natural gum ( Lannea sp.).
