半导体纳米技术创造了终极分析工具:具有单分子灵敏度的纳米孔。该工具以绝对最少的材料和预处理提供了高通量、低成本 DNA 测序的有趣可能性。精致的单分子灵敏度消除了昂贵且容易出错的程序(例如聚合酶链式反应扩增)的需要。相反,纳米孔测序依赖于 DNA 分子通过膜孔移位时产生的电信号。如果每个碱基对都具有特有的电信号,那么表面上可以使用孔来分析序列,方法是在一次读取中报告所有信号,而无需求助于多个 DNA 拷贝。长读长与高易位速度相结合的潜力将使重测序变得廉价,并允许在染色体中进行单倍型分析和甲基化分析。
Semiconductor nanotechnology has created the ultimate analytical tool: a nanopore with single molecule sensitivity. This tool offers the intriguing possibility of high- throughput, low cost sequencing of DNA with the absolute minimum of material and preprocessing. The exquisite single molecule sensitivity obviates the need for costly and error-prone procedures like polymerase chain reaction amplification. Instead, nanopore sequencing relies on the electric signal that develops when a DNA molecule translocates through a pore in a membrane. If each base pair has a characteristic electrical signature, then ostensibly a pore could be used to analyze the sequence by reporting all of the signatures in a single read without resorting to multiple DNA copies. The potential for a long read length combined with high translocation velocity should make resequencing inexpensive and allow for haplotyping and methylation profiling in a chromosome.
