in 2007 proved that
microneedle arrays of 0.5 mm or more penetrate the skin sufficiently to increase diffusion of substances up to 72000Da.5 Many other substances e.g.
Another hollow
microneedle system under investigation is the MicronJet, manufactured by NanoPass Technologies of Nes Ziona, Israel.
FOR MORE THAN 50 YEARS, pharmaceutical companies worldwide have looked to 3M Drug Delivery Systems for ingenious transdermal (
microneedle and drug-in-adhesive) and inhalation (dry powder inhaler and metered-dose inhaler) solutions to help their products meet the needs of the market.
His other paper entitled Structural and Micro fluidic Analysis of MEMS based Out-of-plane Hollow Silicon
Microneedle Array for Drug Delivery has also won Society for Laboratory Automation and Screening (SLAS) Young Scientist Finalist Award in IEEE CASE 2010 in Toronto, Canada.
Instead, the physician positions the device in the vessel of interest, deploys its
microneedle through the blood vessel wall, and delivers the drug directly to the targeted tissue.
They include
MicroNeedle, DuraNeedle, surface, deep fryer, and other specialty probes.
The researchers hope the
microneedle will be the forerunner of small devices for collecting blood that could be permanently attached to the body.
A new experimental
microneedle could soon be used when having immunisations and travel jabs.
But unlike conventional needles that deliver medication to the blood in a matter of seconds, you might have to wear a
microneedle patch longer.
