“…For subsequent silanization of the scaffolds, 1% of (3-aminopropyl)triethoxysilane (APTES) in toluene was used [ 18 , 19 ]. The P1 and P2 scaffolds were treated with 10 mL of the solution for 23 h and the P3 scaffolds were treated with 40 mL for 23 h. All samples were rinsed with toluene, ethanol, ultrapure water, and then dried at 40 °C overnight.…”

Co-Deposition of a Hydrogel/Calcium Phosphate Hybrid Layer on 3D Printed Poly(Lactic Acid) Scaffolds via Dip Coating: Towards Automated Biomaterials Fabrication

Abstract:The article describes the surface modification of 3D printed poly(lactic acid) (PLA) scaffolds with calcium phosphate (CP)/gelatin and CP/chitosan hybrid coating layers. The presence of gelatin or chitosan significantly enhances CP co-deposition and adhesion of the mineral layer on the PLA scaffolds. The hydrogel/CP coating layers are fairly thick and the mineral is a mixture of brushite, octacalcium phosphate, and hydroxyapatite. Mineral formation is uniform throughout the printed architectures and all steps (printing, hydrogel deposition, and mineralization) are in principle amenable to automatization. Overall, the process reported here therefore has a high application potential for the controlled synthesis of biomimetic coatings on polymeric biomaterials.

“…However studies performed on other surfaces, as described above, are expected to be generally applicable to chemically-modified SS surfaces. A widespread procedure to modify SS surfaces consists of grafting silane coupling agents onto the passive oxide film to form an anchoring layer (Landoulsi et al 2011), and to use the amino-end groups to attach various molecules of AF interest, especially polymers. Other procedures of surface functionalistion have been also applied on SS, including the self-assembly of long chain aliphatic molecules with different headgroups, such as carboxylic acids, phosphonic acids and thiols (Shustak et al 2004;Mahapatro et al 2006;Raman and Gawalt 2007;Raman et al 2010;Kruszewski and Gawalt 2011).…”

Review – Interactions between diatoms and stainless steel: focus on biofouling and biocorrosion

2011

There is a considerable body of information regarding bacterially enhanced corrosion, however, this review focuses on diatoms (unicellular algae) whose contribution to biocorrosion is less well studied. The reasons why diatoms have been neglected in studies of biocorrosion in natural waters are discussed and the question whether diatoms should be considered as inert with respect of electrochemical processes is considered. A particular focus is given to the case of stainless steels (SS), which are widely used in variety of applications in natural waters. Basic information on the cell biology of diatoms is included in the review, particularly with respect to their ability to 'sense' and adhere to surfaces. Investigations at the nanoscale are reviewed as these studies provide information about the behavior of cells at interfaces. Recent advances include the use of atomic force microscopy (AFM), although only a few studies have been applied to diatoms. Regarding the electrochemical behavior of SS, the mechanisms by which diatoms influence the potential ennoblement process is discussed. Such studies reveal the association of diatoms, in addition to bacteria, with biocorrosion processes.

“…For instance, silanization with APTES for controlling the interactions between inert stainless steel for the preparation of working or counter electrodes and biocomponents generally involves a pretreatment step that may involve heat, acid etching, and/or chemical treatment. 7 Phosphoric acid chemisorption has been demonstrated for silanization of TiO 2 films. 8 APTES assembling is enhanced via phosphoric acid preadsorption on the anatase TiO 2 film as compared to pristine TiO 2 with no phosphoric acid treatment.…”
