Polymer-based biomaterials are popular due to ease of fabrication and low costs. However, many polymer substrates have undesirable surface properties. The invention provides a procedure to covalently apply a graft polymer to the surface of a polymer substrate by ultraviolet graft polymerization. The graft polymer is formed from monomers such as PEG, AA, monomethoxy acrylate PEG, HEMA, or DMA. Also, mixed monomers may be used to create the graft and the surface properties of the graft may be tailored for different properties, including hydrophobicity, friction coefficient, electroosmotic mobilities and electrophoretic separations. The invention has particular utility in tailoring surface chemistries in ocular lenses and polymer microdevices.

The invention proposes a hoisting-cable drive for a mobile crane, which hoisting-cable drive uses a single bottom-hook block (15) instead of a known double bottom-hook block. However, to prevent this single bottom-hook block (15) from tilting in the two cable lines (9, 10), for example due to possible variations in the elongation of the two cable drives, the hoisting-cable drive according to the invention comprises a kinematic force equilibrium device (17, 21), which can equalize such differences. To this effect, another embodiment of the hoisting-cable drive according to the invention uses a hoisting-cable load pickup (21) within each cable line arrangement so that the rotary speed of the winches (7, 8) can be varied, taking into account any load differences in the individual hoisting-cable lines (9, 10). Furthermore, the invention also proposes that the rotary speed of the winches (7, 8) be adjusted, taking into account the geometric winch states and crane states.
