TissueDB/Materials/Maize Starch
Maize starch (cornstarch) is a fine, dry vegetable powder milled from maize (corn). It is inexpensive and widely available from ordinary food retailers. In surgical simulation it is documented as a dry additive blended into castable silicone to produce a moldable, air-drying suture-pad material.[1]
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Skin | Partial | Partial | Suture Simulator (Almeida) | Blended with acetic (acetoxy) silicone in a 20 g silicone : 11 g maize starch ratio to a homogeneous dough, hand-molded into a 6 cm circular suture pad and air-dried for 48 hours; provides a suturable surface but does not reproduce the different layers of skin tissue (Almeida et al. 2023).[1] |
