Laser pincer for manipulation of micro- and nano-particles (09 RU 86FG 3EV3)
A Russian university based in Samara developed a laser pincer for manipulating micro- and nano-particles in fluid media. It can be used by medical research organizations and innovation companies working with micro- and nanotechnologies. The pincer is low-cost, with a reduced energy consumption.
The university seeks partners for a licence agreement and a joint venture agreement.

The laser pincer is used for laser manipulation of micro- and nano-particles in fluid media. It allows the following operations: linear transportation, rotation with a given angular velocity, simultaneous rotation and transportation of several micro- or nano-particles, laser trap effects. The proposed laser pincer is an effective instrument for bio and medical micro- and nano-technologies.
Commercial analogues available at the world market are based on dynamic light modulators. Instead, the proposed laser pincer applies diffraction optical elements (DOE).
High energy efficiency of DOE allows using a laser with less power as compared with the models applying dynamical light modulators. Laser power of foreign pincers is 3-5 W (for 1-2 mcm particles). The laser of proposed pincer has 200-300 mW power. In this case, a semiconductor laser can be used, thus reducing the pincer cost. Moreover, DOE set is cheaper than a set of dynamical light modulators.
Dynamical light modulator has greater dimensions (10-15 mm) than DOE; it limits the beam parameters and complicates the pincer's optical design. DOE micro-relief has a high resolution and 1-5 mm dimensions for complicated structures.
The developers have a 25-year experience in optical system construction, about 500 scientific publications and over 10 patents.
Innovative Aspects:
Innovation of laser pincer design consists in application of diffraction optical elements instead of dynamical light modulators.
The proposed laser pincer has the following advantages:
- relatively low cost;
- less power consumption;
- simplicity of design.
