A particle coating method includes placing magnetic particles in a vessel, fixing the magnetic particles by a magnetic force caused by a magnetic field generated in the vessel, and forming a coating film on surfaces of the magnetic particles by an atomic layer deposition method. Further, the method preferably includes forming a coating film on surfaces of the magnetic particles by an atomic layer deposition method in a state where the magnetic particles are fixed by the magnetic force in a first direction, thereby obtaining coated magnetic particles, and forming a coating film on surfaces of the coated magnetic particles in a state where the coated magnetic particles are fixed by the magnetic force in a second direction different from the first direction.

A bonding method of bonding two base members together through a bonding film is provided. The bonding method is a method for forming a bonded body in which a first base member and a second base member are bonded together through the bonding film. The bonding method includes: applying a liquid material containing a silicone material composed of silicone compounds onto a surface of at least one of the first and second base members to form a liquid coating on the surface; drying the liquid coating so that it is transformed into the bonding film on the surface of the at least one of the first and second base members; and applying energy to the bonding film so that a bonding property is developed in the vicinity of a surface thereof, to thereby bond the first and second base members together through the bonding film.

Bonding method and bonded body

A bonding method of bonding two base members together through a bonding film having a fine pattern at low cost, and a bonded body with the bonding film which is formed using the bonding method are provided. The bonding method is a method for forming a bonded body in which a first base member and a second base member are bonded together through a bonding film having a predetermined pattern. The bonding method includes: applying a liquid material containing a silicone material composed of silicone compounds onto a surface of at least one of the first and second base members using a liquid droplet ejecting method, to form a liquid coating having a pattern corresponding to the predetermined pattern on the surface; drying the liquid coating so that it is transformed into the bonding film having the predetermined pattern on the surface of the at least one of the first and second base members; and applying energy to the bonding film so that a bonding property is developed in the vicinity of a surface thereof, to thereby bond the first and second base members together through the bonding film.

A base member with a bonding film that can be firmly bonded to an object with high dimensional accuracy and efficiently bonded to the object at a low temperature, a bonding method which is capable of efficiently bonding such a base member and the object at a low temperature, and a bonded body formed by firmly bonding the base member and the object with high dimensional accuracy and therefore being capable of providing high reliability are provided. The base member is adapted to be bonded to an object through the bonding film thereof. The base member includes a substrate, a bonding film containing metal atoms, oxygen atoms bonded to the metal atoms, and leaving groups each bonded to at least one of the metal and oxygen atoms, and having a surface, and an intermediate layer provided between the substrate and the bonding film, the intermediate layer having such a property that its thickness can be changed by applying stress thereto. When energy is applied to at least a predetermined region of the surface of the bonding film, the leaving groups, which exist in the vicinity of the surface within the region, are removed from the bonding film so that the region develops a bonding property with respect to the object.

The purpose of this study was to identify the periodontal regeneration factors in enamel protein shown to induce cementum- and osteo-promotive activities in vivo. The cementum regeneration (CR), a part of periodontal regeneration, was examined by using experimental cavities prepared in a buccal dehiscence dog model. The CR activity was found in the aggregate consisted of sheath proteins along with a small amount of amelogenins separated from newly formed secretory enamel. The sheath proteins were purified to be homogeneous, and examined for the alkaline phosphatase (ALP) inducing activity of human periodontal ligament (HPDL) cells. Application of 17 kDa sheath protein induced ALP activity in HPDL cells. Peptides synthesized from the sheath protein sequence also showed ALP inducing activity. The 17 kDa sheath protein has cell differentiation activity.

A separating method of a bonded body, the bonded body including two base members and a bonding film through which the base members are boded together, enabling to easily and efficiently separating the bonded body into the two original base members is provided. Further, the bonding film contains a silicone material composed of silicone compounds. The separating method includes: preparing the bonded body with the bonding film; and applying energy for separation to the bonding film so that cleavage is generated within the bonding film due to breakage of a part of molecular bonds of the silicone compounds, to thereby separate the bonded body into the first and second base members.
