| 摘要 |
The present invention refers to a biomimetic gellable colloid with customizable composition which may be used as a sectionable support for encoding, processing and microtome sectioning of histological specimens for diagnostic examination. The gellable colloid has a uniformly dispersed phase, it comprises a hydrophilic component and may be gelled upon demand. The colloid may be a nanocolloid or a microcolloid. It may also optionally comprise a hydrophobic component. The hydrophilic component comprises at least a protein component and/or a polymerizable carbohydrate and/or a pre- polymerized carbohydrate, in an aqueous phase. The invention also refers to a process for preparing said gellable colloid, a sectionable matrix configured to handle processing and sectioning of histological samples obtained from said gellable colloid, methods for preparing such a sectionable matrix. The invention also discloses a sectionable code for unambiguous and irreversible identification of histological preparations and the use of a gellable colloid to obtain such a sectionable code. |
