Liquidia Technologies Inc. has raised $25.5 million in equity, according to a Tuesday filing with the Securities and Exchange Commission.

The company is still seeking to raise $27.8 million to meet its goal of $53.3 million.

The money was raised by seven investors.

Liquidia Technologies is a nanotechnology company that designs, develops and manufactures precisely engineered particles and films for various life and material science applications.

The company manufactures engineered particles using PRINT (Particle Replication in Non-Wetting Templates), a particle engineering and manufacturing technology.

The Morrisville-based company is led by Chief Executive Officer Neal Fowler and President and Chief Financial Officer Kevin Gordon.

Gordon joined Liquidia in early February, most recently serving as executive vice president and chief operating officer of Quintiles Transnational Holdings Inc., which is now IQVIA.
