Patent ID: 8501434

Claim:
A method for efficient processing of a non-liquid biological sample with a dynamically moving aqueous-based processing liquid, comprising the steps of: providing a stationary sample support with a hydrophilic surface; providing the non-liquid biological sample fixed on the stationary sample support; providing a moveable wand positioned above the sample support element, the movable wand having a substantially flat hydrophobic surface; applying the aqueous-based processing liquid to the stationary sample support with the non-liquid biological sample; contacting said substantially flat hydrophobic surface of the moveable wand with the aqueous-based processing liquid; forming a substantially contained liquid bridge with the aqueous-based processing liquid between the substantially flat hydrophobic surface of the wand and the hydrophilic surface of the stationary sample support; steadily oscillating the moveable wand back and forth above the stationary sample support and the non-liquid biological sample, therefore steadily oscillating the substantially contained liquid bridge over the stationary sample support and the non-liquid biological sample; and efficiently processing the non-liquid biological sample with the aqueous-based processing liquid.
