Table 2 Atomic concentration of selected elements determined in surface layer of polymers using XPS

From: Grafting of bovine serum albumin proteins on plasma-modified polymers for potential application in tissue engineering

Substrate Treatment (s) Atomic concentration (%)
C O N
HDPE 0 100.0 - -
300 81.8 16.8 1.4
300/BSA 67.9 18.1 14.0
PLLA 0 63.6 36.4 -
300 65.2 33.3 1.5
300/BSA 69.4 17.2 13.4
  1. The atomic concentration of the carbon (C(1 s)), oxygen (O(1 s)), and nitrogen (N(1 s)) in the HDPE and PLLA surface layers of pristine (0), plasma-treated for 300 s (300), and BSA-grafted (300/BSA) was determined by XPS.
