ABSTRACT

Sensitive and affordable diagnostics even for rare diseases are of

certain importance for public health labs in developing countries

but are often not accessible to those who need them most.

Recent interest highlights innovative technological approaches for

overcoming the problem, but these must be balanced by the

efforts and research needed to ensure effective implementation

in the context of only basic laboratory equipment available in

most countries in the developing world. This article discusses the

use of chip-based hybridization arrays for diagnostic purposes

under basic laboratory conditions. It describes a robust and field-

usable chip array design for detection of human pathogens that

couples conventional polymerase chain reaction (PCR) with a DNA

hybridization array.
