ReLIGHT - OR4: OLED photometric station for in-vitro diagnostic analysis

BTP-Tecno is engaged in the re-orientation to medical engineering of its R&D activities carried out at the Plant of Battipaglia (SA), inherited from Alcatel-Lucent and traditionally directed to support the production of equipment for telecommunications.

To this end and for the purpose of mass production, the Company started the design of an innovative platform for the automatic execution of enzyme immunoassay dosing tests, from samples and chemical reagents available on micro plate.

The platform, thought up to automatically carry out  (Walk away) a wide range of methods for testing the immuno-enzyme dosing, will be built in two versions, respectively called “open system” and “closed system”, taking shape as a system able to elaborate chemical reagents on micro plates of different capacity and different manufacturers, or as proprietary system..

The full automation, made possible by the use of “load and go” reagents, permits to have all stages of the analytical session automatically performed. Therefore, the platform is equipped with an embedded logic able to control all the advancement process of the in-process micro plates, each independent of incubation temperature and of agitation. Indipendent needle dispensing is entrusted to rotating arms while the control of dilutions and dosages is entrusted to sensors.

The platform consists of a set of sections and electrical and electromechanical modules dedicated to the execution of well-defined operations, in particular:

 

  • Turning and removable plates for the collection of primary test tubes and reagents;
  • Refrigerating plate for storage of reagents;
  • Rotors;
  • Arms for micro plates handling;
  • Independent needle dispenser;
  • Washing and dilution stations;
  • Rooms for incubation at different temperatures;
  • Photometric reading stations;
  • Barcode reader;
  • Interface with the Laboratory Information System (LIS).

 

In the context of ReLIGHT Project,  BTP-Tecno intends to analyse alternative and innovative solutions for the implementation of the photometric reading station employed in its platform for automation of in vitro diagnostics. In particular, the use of OLED technology in this station may lead to a series of competitive advantages among which:

  • The replacement of the halogen lamp as primary light source with an OLED device, emitting light at different wavelengths, will reduce the operating costs of the platfor
  • The use of several OLEDs, each emitting at a different wavelength, allows to eliminate the filter wheel and the necessary electromechanical actuating mechanism, with evident advantages in terms of cost and reliability of the platform;
  • The use of organic devices both during the light emission (OLED) and in the step of inquiry (photodiodes) allows to realize an extremely compact station, with clear advantages in terms of modularity, integration and portability between platforms with different analytical capacity.
