  Arrays for the Combinatorial Exploration of Cell Adhesion

  摘要：

  A new method for the fabrication of arrays of self-assembled monolayers (SAMs) of alkane thiols (ATs) on gold to combinatorially assay surfaces for cell adhesion is reported. A fluorous SAM, which is both cytophobic and solvophobic, was used as the background between the array features. The resulting solvophobic background permits the application of an assembly after conjugation strategy for fabrication. SAMs containing mixtures of ATs and peptide-terminated ATs were generated. Multiple cell types demonstrated differential and specific binding to these surfaces. Additionally, pluripotent human embryonic stem cells proliferated on surfaces generated by this method.

  Gold nanoparticles decorated with a double‐armed, deep‐cavity calix[4]pyrrole were prepared and fully characterized. Transmission electron microscopy imaging revealed that the average diameter of the particles was approximately 4 nm both before and after attachment of the receptor to the surface. The calix[4]pyrrole‐functionalized nanoparticles exhibited highly elevated sensing behavior (approximately

  制备并充分表征了带有双臂深腔杯[4]吡咯的金纳米颗粒。透射电子显微镜成像显示，在将受体附着于表面之前和之后，颗粒的平均直径均为约4nm。相较于其单体同类物，杯[4]吡咯官能化的纳米粒子表现出很高的感测行为（在二氯甲烷中约为1000倍），同时保持了其客体选择性。受体-纳米颗粒共轭物（nanoreceptor）在添加双酚盐阴离子后显示出明显的聚集，这归因于阴离子介导的颗粒间连接。受体-纳米颗粒共轭物还能够从水层中将氟离子（作为其四丁基铵盐）萃取到有机介质中。

  A method for the construction of arrays from self-assembling monolayers is described. The arrays have particular utility for the screening of peptides ligands that can foster the growth of cells in culture. This technique has been used to identify peptide ligands that foster the growth of human stem cells, which otherwise require an extracellular matrix in order to grow in an undifferentiated state. This also makes possible an assay to identify other such peptides.
