“…We emphasize upon the advantages for processing the powders at low temperature and illustrate the effect of experimental parameters' synthesis on apatite powder characteristics. The non-stoichiometric nanocrystalline apatite bioceramic coatings were deposited on Ti substrates by Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique, considered convenient for the well-protective transfer of novel organic delicate molecules thin films [25,26]. MAPLE ensures good thickness control, patterning facility, and is appropriate for a wide range of biomaterials prone to the decomposition and degradation under direct intense laser irradiation and subsequent exposure to plasma action [25][26][27].…”

“…One can deposit patterned films on a variety of substrate materials with different geometric shapes. The most important requirement of MAPLE process is to minimize and possibly avoid the photonic damage, either of the film or of matrix material during laser interaction and transfer [25][26][27]. MAPLE is a non-contact deposition technique, which eliminates major sources of contamination and can be integrated with other sterile processes [25][26][27].…”

International audienceWe report the deposition by Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique of biomimeticnanocrystalline apatite coatings on titanium substrates, with potential application in tissue engineering.The targets were prepared from metastable, nanometric, poorly crystalline apatite powders, analogousto mineral bone, synthesized through a biomimetic approach by double decomposition process. For thedeposition of thin films, a KrF* excimer laser source was used (λ = 248 nm, τFWHM ≤ 25 ns). The analy-ses revealed the existence, in synthesized powders, of labile non-apatitic mineral ions, associated withthe formation of a hydrated layer at the surface of the nanocrystals. The thin film analyses showedthat the structural and chemical nature of the nanocrystalline apatite was prevalently preserved. Theperpetuation of the non-apatitic environments was also observed. The study indicated that MAPLE isa suitable technique for the congruent transfer of a delicate material, such as the biomimetic hydratednanohydroxyapatite

“…The solvent and solute concentration should be selected so that: the solute can be dissolved to form a dilute, particulate-free solution; most of the laser energy has to be absorbed by the solvent molecules rather than the solute ones; and no photochemical reaction is produced between solvent and solute. By optimization of the MAPLE deposition parameters (laser wavelength, repetition rate, laser fluence, solvent type, solute concentration, substrate temperature, background gas and pressure), the process can proceed without significant material decomposition [6,25,81]. It was demonstrated that MAPLE could provide more crystalline layers as compared to PLD method from the same materials [87].…”

“…The goal is the fabrication of controlled structures (or nanostructures) essential to be used, for instance, in diverse areas such as medical field, packaging, cosmetics, clothing fabrics, food additives, industrial plastics, water treatment chemicals absorbents, biosensors and detectors, or data storage elements [58]. For this purpose, one needs to choose an appropriate deposition method which should depend on the physical-chemical properties of the biomaterial, requirements for film quality, type of the substrate, and the production costs [25].…”

Recent Advances in Biopolymers

This chapter provides an overview of recent advances in the field of laser-based synthesis of biopolymer thin films for biomedical applications. The introduction addresses the importance of biopolymer thin films with respect to several applications like tissue engineering, cell instructive environments, and drug delivery systems. The next section is devoted to applications of the fabrication of organic and hybrid organic-inorganic coatings. Matrix-assisted pulsed laser evaporation (MAPLE) and Combinatorial-MAPLE are introduced and compared with other conventional methods of thin films assembling on solid substrates. Advantages and limitations of the methods are pointed out by focusing on the delicate transfer of bio-macromolecules, preservation of properties and on the prospect of combinatorial libraries' synthesis in a single-step process. The following section provides a brief description of fundamental processes involved in the molecular transfer of delicate materials by MAPLE. Then, the chapter focuses on the laser synthesis of two polysaccharide thin films, namely Dextran doped with iron oxide nanoparticles and Levan, followed by an overview on the MAPLE synthesis of other biopolymers. The chapter ends with summary and perspectives of this fast-expanding research field, and a rich bibliographic database.

“…The solvent must be carefully selected so that it absorbs majority the UV radiation. It has to present a high freezing point and the organic/polymeric material must to present a high solubility in solvent to be deposited (Cristescu et al, 2006). No chemical reaction is permitted between solute (organic polymer) and solvent.…”
