Manganese-doped hollow mesoporous silica nanoparticles loaded with curcumin and an application in periodontal bone tissue repair are provided in the present disclosure, belonging to the technical field of targeted delivery of nanoparticles and bone tissue regeneration. In the present disclosure, alendronate is grafted on the surface of silica nanoparticles to achieve bone targeting, manganese is doped on the nanoparticles by a chemical method, and curcumin is wrapped in the nanoparticles.

Manganese-doped hollow mesoporous silica nanoparticles loaded with curcumin

The invention relates to a device () for holding a sheet-like element () during the stage of introducing it into a workstation () of a forming machine (), such as a waste-ejection station (), the said holding device () comprising a suction member () configured so as to partially retain each sheet () by its rear part during the stage when the said sheet () is introduced into the said workstation (), characterized in that the suction member () has at least two motorized fans () with propellers () installed transversely at the entrance to the workstation (), beneath the plane (P) along which the sheet-like elements move, the axes of rotation (A) of the propellers () of the fans () being substantially parallel to one another and perpendicular to the plane (P) along which the sheet-like elements move, the direction of rotation and the inclination of the propellers () being configured so as to generate a flow of air capable of applying suction to the rear of the lower face of the sheet-like element () during the stage in which the said sheet () is introduced into the said workstation ().
