The invention claimed is: 1. A silicon substrate having a silicon surface comprising a covalently bound monolayer, said monolayer comprising a group of the formula: R1--C≡C--Si wherein Si is a surface silicon atom through which the substituted or unsubstituted alkynyl group is bonded to the silicon surface; and R is hydrogen, hydroxy, halo, cyano, isocyano, C1-C18 alkoxy, C1-C18 carboxy, C1-C 18 alkoxycarbonyl, primary, secondary or tertiary amino, thiol, optionally substituted phosphino, borane (1) or borane (2), or C1-C18 alkylthioether or an optionally substituted C1-C18 alkyl, aryl, heteroaryl or vinyl group; and when R is a substituted group, the group is substituted with one or more substituents selected from the group consisting of hydroxy, halo, cyano, isocyano, C2-C24 alkynyl, C1-C18 alkoxy, C 1-C18 carboxy, C1-C18 alkoxycarbonyl, primary, secondary or tertiary amino, thiol, optionally substituted phosphino, aryl, borane (1) or borane (2), or C1-C18 alkylthioether, halo C1-C18 alkyl, cyano C1-C18 alkyl, isocyano-C1-C18 alkyl, C1-C18 carbamido, or C1-C18 alkylthio group, a C1-C18 ferrocene substituent or another electron donor, a metal chelating ligand or a metal complex thereof, or a biologically significant ligand selected from an antibody, a receptor protein, DNA or RNA, or a DNA or RNA analog capable of forming a double or triple stranded complex with DNA or RNA; or R together with the carbon atoms to which it is attached, forms a 5-, 6-, 7-or 8-membered ring, and wherein the monolayer comprises a pattern wherein some portions of the pattern are no more than about 10 molecules of the group thick. 2. The silicon substrate of claim 1 wherein the monolayer comprises a pattern wherein some portions of the pattern are no more than about 5 molecules of the group thick. 3. The silicon substrate of claim 1 wherein the monolayer comprises a pattern wherein some portions of the pattern are no more than about 1 molecule of the group thick. 4. The silicon substrate of clim 1 further comprising a second covalently bound monolayer, said second monolayer comprising a second group of the formula: R1--C≡C--Si wherein the second monolayer comprises a pattern wherein some portions of the pattern are no more than about 10 molecules of the group thick. 5. The silicon substrate of claim 4 further comprising a plurality of additional covalently bound monolayer, said each additional monolayer comprising a respective group of the formula: R1--C≡C--Si wherein each additional monolayer comprises a pattern wherein some portions of the pattern are no more than about 10 molecules of the group thick. 6. The silicon substrate of claim 1 wherein at least a portion of the covalently bound R groups comprise a biologically significant ligand. 7. A silicon substrate having a silicon surface comprising a pattern of covalently bound monolayers, each of said monolayers comprising an alkyne, wherein at least a portion of each monolayer is no more than about 5 molecules of the alkyne wide.
