  Photochemical Mineralization of Europium, Titanium, and Iron Oxyhydroxide Nanoparticles in the Ferritin Protein Cage

  摘要：

  The Fe storage protein ferritin was used as a size-constrained reaction vessel for the photoreduction and reoxidation of complexed Eu, Fe, and Ti precursors for the formation of oxyhydroxide nanoparticles. The resultant materials were characterized by dynamic light scattering, gel electrophoresis, UV-vis spectroscopy, and transmission electron microscopy. The photoreduction and reoxidation process is inspired by biological sequestration mechanisms observed in some marine siderophore systems.

  This invention provides methods by which biologically derived DNA sequences in a mixed sample or in an arrayed single sequence clone can be determined and classified without sequencing. The methods make use of information on the presence of carefully chosen target subsequences, typically of length from 4 to 8 base pairs, and preferably the length between target subsequences in a sample DNA sequence together with DNA sequence databases containing lists of sequences likely to be present in the sample to determine a sample sequence. The preferred method uses restriction endonucleases to recognize target subsequences and cut the sample sequence. Then carefully chosen recognition moieties are ligated to the cut fragments, the fragments amplified, and the experimental observation made. Polymerase chain reaction (PCR) is the preferred method of amplification. Another embodiment of the invention uses information on the presence or absence of carefully chosen target subsequences in a single sequence clone together with DNA sequence databases to determine the clone sequence. Computer implemented methods are provided to analyze the experimental results and to determine the sample sequences in question and to carefully choose target subsequences in order that experiments yield a maximum amount of information.

  本发明提供了无需测序即可确定和分类混合样本或阵列单序列克隆中生物衍生 DNA 序列的方法。这些方法利用精心选择的目标子序列（通常长度为 4 至 8 个碱基对）的存在信息，以及样本 DNA 序列中目标子序列之间的长度，再加上包含样本中可能存在的序列列表的 DNA 序列数据库，来确定样本序列。首选方法是使用限制性内切酶识别目标子序列并切割样本序列。然后将精心选择的识别分子连接到切割的片段上，扩增片段并进行实验观察。聚合酶链反应（PCR）是首选的扩增方法。本发明的另一个实施方案是利用单序列克隆中存在或不存在精心选择的目标子序列的信息以及 DNA 序列数据库来确定克隆序列。本发明提供了计算机实现的方法来分析实验结果，确定有关的样本序列，并仔细选择目标子序列，以便使实验产生最大的信息量。
