Adsorption Behavior of Amino Acids on a Stainless Steel Surface

Effects of carboxyl groups on the adsorption behavior of low-molecular-weight substances on a stainless steel surface

“…The results of these studies indicate an important role of the carboxyl group of acidic amino acid residues in the adsorption to the metal surface, particularly in the acidic pH region [1,5]. We have also shown that peptides having plural acidic amino acid residues are irreversibly adsorbed on a stainless steel surface [1,5], while the adsorption of acidic amino acids is reversible [6]. A number of investigators have also pointed out the importance of a carboxyl group in the adsorption of organic compounds such as benzoic acid, phthalic acid, and salicylic acid to metal oxide particles and studied the chemical nature of these compounds in the adsorbed state [8][9][10][11][12][13][14][15][16][17].…”

“…Namely, 1 ml of carboxylic acid solution was transferred into the ATR cell having a Ge crystal window, and 256 spectral scans were collected over the range of 900-4000 cm −1 with a 4 cm −1 resolution. For measurement of the spectra by a diffuse reflection technique (DR-IR) [6], the phthalic acid powder was mixed with approximately a 40-fold amount of KBr powder and ground into fine powder. The resulting powder was packed in a stainless steel cup and scanned 128 times over the range of 650-4000 cm −1 with a 4 cm −1 resolution.…”

“…Thus, a better understanding of the mechanism that controls adsorption to a solid surface would be desirable in terms of the cleaning conditions. We have attempted to clarify the adsorption behavior of proteins [1][2][3][4], their components [5,6], and others [7] on a stainless steel surface. The results of these studies indicate an important role of the carboxyl group of acidic amino acid residues in the adsorption to the metal surface, particularly in the acidic pH region [1,5].…”

Interactions of biomolecules with inorganic materials: principles, applications and future prospects

“…1). 30,[32][33][34][35][36] In this review we briefly present a few examples of our current level of understanding of inorganic materials-biomolecule interactions from the biomineralization perspective before discussing the role that combinatorial approaches such as phage and cell display methods can play in identifying peptides that interact with a wide range of natural and nonnatural mineral surfaces. Here, the emphasis will be on the extent of understanding that can be obtained from such studies.…”

Adsorption characteristics of various organic substances on the surfaces of tantalum, titanium, and zirconium

“…On the other hand, adsorption characteristics of proteins are important relative to the performance of immobilized enzymes, biosensors, and enzyme-linked immunoadsorbent assays [1]. Thus, considerable interest has developed in the adsorption of various organic substances onto solid surfaces [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The importance of functional dissociative groups such as carboxyl and amino groups has been noted [10][11][12][13][14]20].…”
