Low Cost Cytometer Based on a Dvd Pickup Head
نویسنده
چکیده
Cytometry is a process that allows for measuring characteristics of single biological cells [1]. In this paper we report on a novel cytometric cell detector using a DVD pickup head. The system uses a microfluidic chip with a flow cell that allows for hydrodynamic focusing of the sample flow. The reflected optical signal intensity is influenced by particles that pass the beam and is measured directly in the pickup. Measurement results on a mixture containing erythrocytes and polystyrene particles are presented and the cytometric separation is shown in a two-parameter histogram.

Measurement of Cantilever Displacement Using a Compact Disk /Digital Versatile Disk Pickup Head
We use the optical pickup head of a commercial compact disk (CD)/digital versatile disk (DVD) read only memory (ROM) drive to detect the vertical displacement of micro fabricated cantilever in atomic force microscopy (AFM). Both the contact and AC modes of AFM are demonstrated. The single atomic steps of graphite can be resolved, indicating that atomic resolution in the vertical displacement de...
متن کاملThe fuzzy multi-depot vehicle routing problem with simultaneous pickup and delivery: Formulation and a heuristic algorithm
In this paper, the fuzzy multi-depot vehicle routing problem with simultaneous pickup and delivery (FMDVRP-SPD) is investigated. The FMDVRP-SPD is the problem of allocating customers to several depots, so that the optimal set of routes is determined simultaneously to serve the pickup and the delivery demands of each customer within scattered depots. In the problem, both pickup and delivery dema...
متن کاملSingle-cell isolation using a DVD optical pickup
A low-cost single-cell isolation system incorporating a digital versatile disc burner (DVD RW) optical pickup has been developed. We show that these readily available modules have the required laser power and focusing optics to provide a steady Gaussian beam capable of optically trapping micron-sized colloids and red blood cells. Utility of the pickup is demonstrated through the non-destructive...

A low-cost and high-precision straightness measurement system using a DVD pick-up head has been developed in this research. By removing its objective lens the pick-up head of a commercial DVD player possesses excellent properties of stable laser power, collimated laser beam, circular Gaussian distribution and sensitive photodetectors. A moving knife-edge piece is placed between the pick-up head...
متن کاملA Measuring Method for Angular Displacement Based on Correlation Algorithm
The existing angular displacement measurement methods rely on the manufacturing precision of the fixedplate and moving-plate with high manufacturing cost, and it is difficult to overcome a static error and drift for the static measurement method. A kind of angular displacement measuring method based on correlation algorithm is presented with the characteristics of a low manufacturing cost, high...
