背景技术Background technique
对微小物体的光学捕获和筛选一直是光学领域的研究热点。光学梯度力在各种光学捕获技术中扮演着重要的角色，例如通过光学梯度力实现的光镊和光学捆绑等。然而，光学梯度力具有产生设备复杂、不可调谐和难以捕获和筛选纳米尺寸分子等缺点。2008年，Ward,T.J.等提出通过圆偏振光产生的光学梯度力可以捕获和分离具有纳米尺寸的手性分子。但是，圆偏振入射光仍然需要使用复杂的设备来产生，不利于系统的实际应用；且其捕获和分离的纳米尺寸分子必需具有手性结构，因此限制了其作用对象的范围。所以，本发明提出在位于二氧化钒衬底平板上方的微粒表面覆盖纳米尺寸分子，使其在线偏振平面光波照射下在微粒周围产生非梯度光学力；然后，利用二氧化钒晶格结构随外加光场、电场、温度场、和压力场改变而变化的特性，调谐二氧化钒衬底平板上方微粒受到的非梯度光学力大小和方向，从而实现对附着在微粒表面的纳米尺寸分子的捕获和筛选，其中纳米尺寸分子可以为非手性结构。Optical trapping and screening of tiny objects has always been a research hotspot in the field of optics. Optical gradient force plays an important role in various optical trapping technologies, such as optical tweezers and optical bundling through optical gradient force. However, optical gradient forces have the disadvantages of complex devices, non-tunable devices, and difficulty in trapping and screening nanometer-sized molecules. In 2008, Ward, T.J. et al proposed that the optical gradient force generated by circularly polarized light can capture and separate chiral molecules with nanometer size. However, the circularly polarized incident light still needs to be generated by complex equipment, which is not conducive to the practical application of the system; and the nano-sized molecules captured and separated must have a chiral structure, thus limiting the scope of its target. Therefore, the present invention proposes to cover the surface of the particle above the vanadium dioxide substrate plate with nano-sized molecules, so that it can generate non-gradient optical force around the particle under the irradiation of the linearly polarized plane light wave; The characteristics of light field, electric field, temperature field, and pressure field change, and the size and direction of the non-gradient optical force on the particles above the vanadium dioxide substrate plate are tuned, so as to realize the capture and absorption of nanometer-sized molecules attached to the particle surface. Screening where nanoscale molecules can be achiral.

具体实施方式Detailed ways
为使得本发明的技术方案的内容更加清晰，以下结合技术方案和附图详细叙述本发明的具体实施方式。其中的材料生长技术包括：磁控溅射，电子束蒸发，金属有机化合物化学气相沉淀，气相外延生长，和分子束外延技术等常用技术。In order to make the content of the technical solution of the present invention clearer, the specific implementation manners of the present invention will be described in detail below in combination with the technical solution and the accompanying drawings. The material growth techniques include: magnetron sputtering, electron beam evaporation, chemical vapor deposition of metal-organic compounds, vapor phase epitaxy, and molecular beam epitaxy.
实施例1Example 1
首先，通过材料生长工艺产生微粒1，如附图1(a)所示。其中微粒的几何形状和尺寸可以采用有限时域差分法、有限元法等算法确定。First, particles 1 are produced through a material growth process, as shown in Fig. 1(a). The geometric shape and size of particles can be determined by finite time domain difference method, finite element method and other algorithms.
其次，在微粒1外表面附着纳米尺寸分子2，如附图1(b)所示。Secondly, nanometer-sized molecules 2 are attached to the outer surface of the particle 1, as shown in FIG. 1(b).
然后，将表面附着纳米尺寸分子2的微粒1置于二氧化钒衬底平板3表面上方，距离为l(l>0)，当入射光为线偏振平面波且二氧化钒衬底平板3为单斜结构的绝缘体态时，处于二氧化钒衬底平板3上方的微粒1周围的玻印亭矢量为非对称分布，即微粒1上的总玻印亭矢量不为零，产生沿入射光方向指向右前方的非梯度光学力，使微粒1沿入射光方向的右前方运动，进而带动附着在微粒1表面的纳米尺寸分子2沿入射光方向的右前方运动，如附图2(a)所示。Then, the particles 1 with nanometer-sized molecules 2 attached to the surface are placed above the surface of the vanadium dioxide substrate plate 3 at a distance of l (l>0). When the incident light is a linearly polarized plane wave and the vanadium dioxide substrate plate 3 is a single In the insulator state of oblique structure, the Poynting vectors around the particles 1 above the vanadium dioxide substrate plate 3 are distributed asymmetrically, that is, the total Poynting vectors on the particles 1 are not zero, resulting in pointing along the incident light direction The non-gradient optical force in the right front makes the particle 1 move along the right front of the incident light direction, and then drives the nano-sized molecules 2 attached to the surface of the particle 1 to move along the right front of the incident light direction, as shown in Figure 2(a) .
之后，通过光照、通电、加热和加压等方式将二氧化钒衬底平板3的单斜结构的绝缘体态转化为四方结构的金属态，使微粒1表面的总玻印亭矢量方向和大小发生改变，产生沿入射光方向指向左前方的非梯度光学力，使微粒1带动附着在其表面的纳米尺寸分子2沿入射光方向的左前方运动，如附图2(b)所示。Afterwards, the insulator state of the monoclinic structure of the vanadium dioxide substrate plate 3 is transformed into a metal state of the tetragonal structure by means of light, electricity, heating, and pressure, etc., so that the direction and size of the total Poynting vector on the surface of the particle 1 change Change to produce a non-gradient optical force pointing to the left front along the incident light direction, so that the particle 1 drives the nanometer-sized molecules 2 attached to its surface to move along the left front of the incident light direction, as shown in Figure 2(b).
最后，通过降温、光照等方式使二氧化钒衬底平板3由四方结构的金属态变回单斜结构的绝缘体，此时微粒1受到的非梯度光学力又变回了沿入射光方向指向右前方的非梯度光学力，微粒1带动纳米尺寸分子2沿入射光方向的右前方运动，如附图2(c)所示。Finally, the vanadium dioxide substrate plate 3 is changed from the metal state of the tetragonal structure back to the insulator of the monoclinic structure by means of cooling, lighting, etc. At this time, the non-gradient optical force on the particle 1 changes back to pointing to the right along the direction of the incident light. For the non-gradient optical force in the front, the particle 1 drives the nano-sized molecule 2 to move along the right front of the incident light direction, as shown in Fig. 2(c).
这样我们通过改变二氧化钒衬底平板3中二氧化钒的晶格结构，控制微粒1在入射光场中的运动轨迹，最终实现了对附着在微粒1表面的纳米尺寸分子2的可调谐捕获和筛选。In this way, by changing the lattice structure of vanadium dioxide in the vanadium dioxide substrate plate 3, we control the trajectory of the particle 1 in the incident light field, and finally realize the tunable capture of the nanometer-sized molecules 2 attached to the surface of the particle 1 and filter.
本发明系统主要由光源4、显微镜5和光学力显示器6构成。测试前先将二氧化钒衬底平板3置于装有水或油的样品池7的底部，然后将表面附着纳米尺寸分子2的微粒1置于样品池7内，且置于二氧化钒衬底平板3上方。光源4产生线偏振平面波从样品池7的侧壁进入，水平照射微粒1，实现对表面附着纳米尺寸分子2的微粒1的抓获和操纵。显微镜5可以用来观测微表面附着纳米尺寸分子2的微粒1在入射光作用下所产生的运动轨迹。线偏振平面波在表面附着纳米尺寸分子2的微粒1产生的非梯度光学力由光学力显示器6测得。本发明系统同时还包括控温器8、CCD摄像机9、监视器10、计算机11、和录像机12等(附图3所示)。利用CCD摄像机9对线偏振平面波照射下的表面附着纳米尺寸分子2的微粒1进行实时监测，并将所得的视频信号在显示器显示。录像机12可以用来记录图像。样品池7与控温器8相连，二氧化钒衬底平板3中的二氧化钒的晶格结构随样品池7的温度变化而改变。计算机11可以存储显微镜5所采集的视场信息。The system of the present invention is mainly composed of a light source 4 , a microscope 5 and an optical force display 6 . Before the test, the vanadium dioxide substrate plate 3 is placed at the bottom of the sample pool 7 filled with water or oil, and then the particles 1 with nanometer-sized molecules 2 attached to the surface are placed in the sample pool 7 and placed on the vanadium dioxide liner. Bottom plate 3 tops. The light source 4 generates a linearly polarized plane wave that enters from the side wall of the sample cell 7 and irradiates the particle 1 horizontally, so as to capture and manipulate the particle 1 attached to the surface of the nanometer-sized molecule 2 . The microscope 5 can be used to observe the trajectory of the microparticles 1 attached to the nanometer-sized molecules 2 on the microsurface under the action of incident light. The non-gradient optical force produced by the linearly polarized plane wave attached to the surface of the particle 1 with nanometer-sized molecules 2 is measured by the optical force display 6 . The system of the present invention also includes temperature controller 8, CCD camera 9, monitor 10, computer 11, and video recorder 12 etc. (shown in accompanying drawing 3) simultaneously. The CCD camera 9 is used for real-time monitoring of the particles 1 with nanometer-sized molecules 2 attached to the surface irradiated by the linearly polarized plane wave, and the obtained video signal is displayed on the monitor. Video recorder 12 may be used to record images. The sample pool 7 is connected with the temperature controller 8 , and the lattice structure of the vanadium dioxide in the vanadium dioxide substrate plate 3 changes with the temperature of the sample pool 7 . The computer 11 can store the field of view information collected by the microscope 5 .
