1. A microfluidic device comprising:
- a glass, glass-ceramic, or ceramic structure, said structure including one or more passages defined therein;
at least one first passage accessible through at least one first port;
wherein said first passage contains at least one solid object disposed therein, said solid object including a material having a coefficient of thermal expansion differeing from the glass, glass-ceramic, or ceramic of said structure, said solid object resting in said first passage substantially without compressive stress from an inside surface of said passage at room temperature.

16. A method of making a microfluidic device comprising glass, glass-ceramic, or ceramic and having a solid structure incorporated therein having a thermal expansion coefficient differing from said glass, glass-ceramic, or ceramic, the method comprising:
-
providing a solid structure for incorporation into a microfluidic device; forming, in a glass, glass-ceramic, or ceramic material, an open-ceiling passage; positioning said solid structure in said passage; enclosing said solid structure within said passage so as to form an enclosed passage within said device containing said solid structure. - View Dependent Claims (17, 18, 19, 20)
