Pieter, I dunno if I buy that as being DIY. I think it's great that
you have built a cheaper product, and that you're engaged with DIY.
But if a venture-backed company counts as DIY, doesn't that make all
the pharma techs and Big Bio also DIY? That wouldn't make sense to me.

Amplino may be the ultimate garage project. Three DIY bio-hackers have
created a mobile malaria testing kit they claim can identify different
strains of malaria with higher accuracy than existing rapid diagnostic
tests.
The testing device is connected via Bluetooth to a mobile phone,
making it possible to track malaria outbreaks and the spread of
particular strains. The team just won 40,000 EUR ($52,000) in the
Vodafone Mobile for Good competition to further develop the kit.
Amplion’s young founders Jelmer Knossen, Wouter Bruins, and Pieter van
Boheemen have backgrounds in bio-informatics/mechanical engineering,
cell biology, and functional genomics respectively. The group became
fascinated by the DIYBio movement, which blends biology expertise with
electronics, software development, and open source principles.
Amplino’s team started to look at a technique called PCR, which copies
a segment of DNA billions of times so that it can be analyzed. PCR is
a well-established technique used in criminal DNA testing, disease
diagnosis, and even testing whether food is halal.
A $600 “Build it yourself” OpenPCR machine already existed. The team
decided to go one step further and develop a mobile device to do
real-time PCR plus diagnosis of malaria. When you add a DNA binding
dye to the multipled DNA mixture and shine light of a specific
wavelength on it, the mixture will emit light when the malaria
parasite is present.
In fact, the technology can detect any kind of pathogen, not just
malaria, depending on the selection of a chemical component called a
primer used in the device. A commercial real-time PCR setup can cost
up to $30,000. Amplino made one for $60.
Malaria is a massive problem in the developing world. WHO estimates
that up to 1 million people die each year from the disease, the
majority of which are children in sub-Saharan Africa. The main methods
of testing in the developing world are rapid diagnostic blood tests,
which look like a pregnancy test and can be easily used in the field,
and microscopy of a blood smear. The main measure of accuracy of a
malaria test is its sensitivity, in other words what percentage of
infected people are correctly identified. Other factors in assessing a
testing system include the number of false positives, storage life,
and whether refrigeration is required.
Rapid diagnostic tests are less sensitive than lab tests and cannot
identify different types of malaria. Microscopy is more accurate but
requires the samples to be sent to a laboratory where trained health
professionals review the blood samples. Incorrect diagnosis means that
the limited supply of malaria drugs is not allocated optimally.
Over-prescription can also lead to drug resistance. However, testing
at the point of care can still result in higher levels of correct
patient treatment than more accurate, but slower, lab testing.
Amplino’s test is more sensitive than rapid diagnostic tests but can
be used by non-medical staff for immediate diagnosis in the field. It
can also detect malaria in pregnant women. During pregnancy, a woman’s
immune system is suppressed, making her twice as likely to die from
malaria. The parasites that cause the disease can hide in the
placenta, making them much harder to detect.
Amplino estimates that the final mobile testing device will cost about
$250, while the cartridge required per test costs between 50 cents and
$1. Getting the device to market is still a long road. While the core
PCR technology being used is not new, all medical devices need to be
certified. This process, plus getting the prototype ready for
manufacturing, could cost up to 1.5 million EUR over the next few
years.
There are not many competing devices. InstantLabs makes a portable,
real-time PCR system, but the company seems to focus mainly on the
food safety industry. Lava Amp makes a $300 machine to run PCR but not
to diagnose a particular disease.
“Our ultimate goal would be to get money from the Gates foundation,”
said Bruins. ”We need strategic, not purely financial investors.” The
Vodafone prize will allow the team to produce a version of the
prototype that can be manufactured on a large scale (they estimate
this will take six months) and test it in the field in Burkina Faso.
Amplino is not seeking to patent the technology. “I actually have two
patents pending (for other technologies), ” Bruins explained. “But is
a patent really fit for our mission? Maybe we need to ditch the whole
patent approach.”
Amplino was founded in 2012, is based in Leiden in the Netherlands,
has three employees, and is privately funded.
