Monofilament of PP was spun and  drawn. Its modification was carried out by the  grafting vinylimidazole using simultaneous radiation  grafting method. The effect of radiation dose,  monomer concentration, and the grafting medium on the  degree of grafting was evaluated. Grafted suture was  characterized using several techniques, such as  infrared spectroscopy, X-ray diffraction,  differential scanning calorimetry, scanning electron  microscopy. It was found that the grafts are confined  to the amorphous region and the crystalline regions  remain intact. The tenacity slightly decreases  whereas the elongation increases with the increase in  the degree of grafting. TGA study shows that the  stability of the sutures is enhanced by the grafting  process. These sutures have reasonably good water  uptake. They are subsequently immobilized with an  antimicrobial drug, ciprofloxacin. The modified  suture releases the drug over a period of 4¿5 days.  The antimicrobial activity of the modified suture is  determined against E. coli by the zone of inhibition  technique.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838343792\"\u003e\u003ch3\u003eUse of high energy radiation\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838343792","offer_id":39498894540893,"sku":"9783838343792","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/0bf57ec0-934b-4a93-84fe-792b93350dfa.jpg?v=1769668493","url":"https:\/\/shop.autorenwelt.de\/products\/development-of-antimicrobial-suture-of-polypropylene-von-syed-gulrez","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
