Surface stabilization of biosensors

A method of preparing a sensor apparatus, the method comprising:

• applying a cleaning solution through a flow cell over a semiconductor device the semiconductor device including an array of field effect transistor (FET) sensors, and an array of wells formed over the array of FET sensors;
• the array of wells and array of FET sensors forming a sensor chip with a sensor chip surface;
• applying a saccharide solution through the flow cell, the solution including a saccharide;
• and
• removing the saccharide solution from the flow cell, a layer of the saccharide remaining over the sensor chip surface.
