Albumin production by primary rat hepatocytes cultured on undecanoic acid-terminated porous Si (Si—(CH2)10COOH), ozone-oxidized porous Si (Si-OH), and on a crystalline Si wafer (Flat Si) over the course of 8 days. All surfaces contained pre-adsorbed collagen I, and cells were overlayed with a collagen gel for maintenance of cell function. Double asterisks (**) denotes data points with significantly higher albumin production from cells cultured on undecanoic acid-terminated porous Si in comparison to cells on flat Si. Single asterisk (*) denotes data points with significantly higher albumin production from cells on flat Si in comparison to ozone oxidized porous Si. p < 0.05
