Abstract:
The present invention relates to molecularly imprinted metal nanoparticles for binding with a serum amyloid P component protein and, more specifically, to metal nanoparticles for binding specifically with a serum amyloid P component protein (SAP) having a structure in which an azide-terminated self-assembled molecular layer is formed on the metal nanoparticle and a molecularly imprinted layer is formed on the azide-terminated self-assembled molecular layer. The nanoparticles bound with SAP of the present invention has an effect of inhibiting SAP binding to amyloid fibrils and mitigates the onsel of Alzheimer′s disease. The particles manufactured in the present invention can be used for SAP detection and concentration measurement together with an ability for inhibiting SAP binding to the amyloid fibrils.

Abstract:
PURPOSE: A metal hydroxide based flame retardant-silica nanostructure, a manufacturing method thereof, and a flame-resistant insulating material including thereof are provided to improve dispersibility within a polymer resin of the metal hydroxide based flame retardant. CONSTITUTION: A manufacturing method of a metal hydroxide based flame retardant-silica nanostructure comprises next steps: forming an emulsion solution; dispersing the metal hydroxide based flame retardant into basic silicate aqueous solution; and reacting silicate solution with the emulsion solution. The basic silicate includes more than one kind which is selected from lithium silicate, sodium silicate, potassium silicate, magnesium silicate and sodium silicate potassium. The metal hydroxide based flame retardant includes more than one kind which is selected from magnesium hydroxide, calcium hydroxide, and aluminium hydroxide. A content amount of the metal hydroxide based flame retardant is 4-40 parts by weight based on 100.0 parts by weight of the basic silicate solution. The metal hydroxide based flame retardant-mixing silica nanostructure includes 1-60 parts by weight of the metal-hydroxide group flame retardant based on 100.0 parts by weight of silica nanoparticle.
