Construction and operation of a microrobot based on magnetotactic bacteria in a microfluidic chip

Magnetotactic bacteria (MTB) are capable of swimming along magnetic field lines. This unique feature renders them suitable in the development of magnetic-guided, auto-propelled microrobots to serve in target molecule separation and detection, drug delivery, or target cell screening in a microfluidic chip. The biotechnology to couple these bacteria with functional loads to form microrobots is the critical point in its application. Although an immunoreaction approach to attach functional loads to intact MTB was suggested, details on its realization were hardly mentioned. In the current paper, MTB-microrobots were constructed by attaching 2 μm diameter microbeads to marine magnetotactic ovoid MO-1 cells through immunoreactions. These microrobots were controlled using a special control and tracking system. Experimental results prove that the attachment efficiency can be improved to ∼30% via an immunoreaction. The motility of the bacteria attached with different number of loads was also assessed. The results show that MTB can transport one load at a velocity of ∼21 μm/s and still move and survive for over 30 min. The control and tracking system is fully capable of directing and monitoring the movement of the MTB-microrobots. The rotating magnetic fields can stop the microrobots by trapping them as they swim within a circular field with a controllable size. The system has potential use in chemical analyses and medical diagnoses using biochips as well as in nano/microscale transport.     

Electrowetting on dielectric driven droplet resonance and mixing enhancement in parallel-plate configuration

This study experimentally verifies that the mixing process in a droplet can be enhanced by driving the droplet at resonant frequencies and at alternating driving frequencies using a parallel-plate electrowetting on dielectric device. The mixing time, which is defined as the time required for reaching the well-mixed state, in a resonant droplet is found to be significantly shorter than that in a non-resonant droplet. Besides, it is also found that a higher driving potential leads to a better mixing effect, especially at resonant frequencies. Furthermore, when a droplet is driven by alternating two driving frequencies, especially two resonant frequencies, the mixing efficiency is found to be significantly enhanced for a specific alternating duration of these two frequencies.

科技投入与区域经济协调发展评价研究

科技投入是科技活动的源头,是实现产业升级、推动经济发展的重要前提.以黑龙江省为例,通过建立科技投入与区域经济发展评价指标体系,运用因子分析方法对黑龙江省1999-2008年科技投入与区域经济发展的综合水平进行了测度,并根据测度综合水平与回归分析结果,利用所构建的科技投入和区域经济协调发展度模型,对科技投入与经济发展协调状况进行定量测算,最后基于实证分析科技投入与经济协调发展中存在问题,并结合实际提出若干建议.     

技术空间溢出对全社会能源效率的影响分析

本文依据2000-2010年中国30省面板数据,从新经济地理学视角,引入空间变量,运用面板方法估算了技术空间溢出对全社会能源效率的影响,研究结果表明:全社会能源效率存在空间相依性,外商直接投资由东部经中部向西部的梯次溢出对全社会能源效率有显著的正向影响,国内技术转让和R&D人员有助于提升西部地区全社会能源效率,因此,就技术节能而言,东部地区应以外商直接投资为主,而中西部地区则优先考虑国内技术转让。此外,考虑技术空间溢出后,东西部仍存在空间滞后现象,说明有其他确定性溢出因素的影响,有待进一步深入研究。

一株油微藻——小球藻的纯化鉴定与培养基的筛选

从南京工业大学生物与制药工程学院获得一株小球藻藻种,经划线培养数代后,得到分离纯化的小球藻,18S rDNA鉴定确定其种属为普通小球藻.小球藻的常见几种培养基筛选结果表明,BG11培养基最适合该小球藻的生长.用牛粪浸出液代替传统培养基培养小球藻的梯度对照实验中,发现牛粪浸出液培养小球藻的效果很好,且浓度越高,生长状况越好.同时还对小球藻的粗脂含量做了测定,每克小球藻干粉中粗脂的含量约为0.206 g,占小球藻干重的20％左右.本研究为新能源的开发和利用积累了信息.
