method can be up to 90 pieces per hour. Moreover, wax printing
methods require rather expensive printers and heating equipment,
whereas this wax dipping method uses only a common hot plate
or similar heating device.
Besides being a simple and rapid process for the fabrication of
the PAD, the proposed wax dipping protocol is also inexpensive
and environmentally friendly. Every developing country can set
up the wax dipping method for fabrication of PADs. Beeswax is
inexpensive and can be obtained worldwide, and the system setup
requires only a common hot plate, iron mould and permanent
magnet. The total cost for a piece of PAD fabrication by wax dipping
is inexpensive at less than $0.05 US per piece. Some materials
are reusable, such as the iron moulds, permanent magnets, and
glass slides. From our point of view, the wax dipping method is
a novel alternative technique to produce a simple and low-cost
