Patent ID: 8455088

Claim:
A biostable nanofiber formed from a compound of the formula (Formula I): [(R 2 O) 3 —Si—R 3 ] z —Y—[(R 1 ) m —O x ] q —Y′—[R 3 —Si—(OR 2 ) 3 ] z where x and z are each independently 0 or 1; m is 1 to 18; q is 1 to 200; R 1 , R 2 and R 3 are each independently an organic group; and Y and Y′ are selected together from the group consisting of: —O—(C═O)— for Y and —(C═O)— for Y′ where z=1; —(NR 4 )—(C═O)—(NH)— for Y and Y′, where z=1, and R 4 is an organic group; and —N—[CH 2 —(CHOH)—CH 2 —O—R 3 —Si—(OR 2 ) 3 ] 2 for Y and Y′, where z=0; where the biostable nanofiber is produced by a spinning process.
