Green Eyes: development of [the] ProbeGuard anti-biofouling device

Green Eyes 1

Business Description

Green Eyes markets aquatic monitoring systems and services to academic, environmental consulting, sewage treatment and federal, state, and local government water monitoring agencies.


Green Eyes sought to address a longstanding biofouling problem for aquatic instrumentation with the development and commercialization of ProbeGuard, a product that controls biofouling on various moored aquatic instruments by enclosing sensors in a chamber that is periodically treated with a biocide after data is collected. The chamber is opened and flushed with ambient water before sampling to insure data integrity.


Biofouling was identified by the Alliance for Coastal Technologies (ACT) as a key problem for observing systems that was yet to be solved. Through MIPS, Green Eyes refined ProbeGuard, which addresses this problem by using two concentric cups that form a protective sensor “garage.” Both the outer (static) and inner (rotating) cups have windows that align to allow free communication with the ambient water in sampling mode and are staggered in protected mode to block the sensors from the ambient water. Upon closing the windows, a biocide is delivered by one to four compact and highly efficient proprietary pumps. All activities of ProbeGuard are microprocessor-controlled; all actions are logged on non-volatile, on-board memory.

The successful project has enabled Green Eyes to market ProbeGuard, which reduces servicing costs by 50-75 percent while improving data quality. The system also allows real-time access to data.

The MIPS project enabled Green Eyes to create 16 jobs in Maryland.

Leading up to (and beyond) the Maryland Industrial Partnerships (MIPS) 25th Anniversary Gala, we will frequently profile one (or more) of the 500+ companies that have utilized MIPS funding to bring innovations to market and create jobs in Maryland.
