A fluid dispensing system (100) for at least biological applications, e.g., oligonucleotides, peptide nucleic acids ('PNA'), proteins, polysaccharides; polypeptides, inorganic solutions, microelectromechanical systems (MEMS), optical sensors, and other applications. The dispensing system includes a fluid dispensing apparatus for applying selected fluids in a predetermined manner to form a plurality of spots based upon one or more of the selected fluids on a surface of a substrate. The apparatus comprises an elongated member (101) having at least a tip portion (109), which extends from the elongated member. The apparatus also has an etched trench (107) extending along a portion of a length of the elongated member to the tip to form an opening (105) defined on the tip portion and coupled to the etched trench. A flexible region (103) is defined within the elongated member to allow the tip to adjust in position upon contact with the surface of the substrate. |
