University General Hospital Attikon, Athens, Greece.

Below you can find Report of the analyses concerning the use of DALF NC4 in the ICU of the University General Hospital Attikon, Athens, Greece.

The purpose of this study is to gather data in order to proof the activity of DALF NC4 to achieve a higher level of hygiene in hospital environments. Due to a lack of personnel, money and therefore time the hygienic situation in hospitals is very poor. The day to day cleaning is carried out very poorly. For example: the ICU of
the Attikon will be cleaned only once a day. The risks of a bacterial outbreak are extremely large.

To fight the bacteria in the ICU the hospital decided to treat the human contact points at the beds with copper. The results were good, the human contact points at the bedside were almost free of bacteria. However, the walls, floor and medical devices seemed to be severely infected with all kinds of bacteria.

DALF NC4 is a waterbased photocatalystic nanocoating, with a durability of 3 years (1 year on Human Contact Points). DALF NC4 is sprayed on all surfaces in Room B on the 9th of august 2013. After the treatment with DALF NC4 the cleaning with only water will be sufficient to have a hygienic acceptable situation. DALF NC4 is a proven method within other critical branches, like the food processing branche, to bring general hygiene to a much higher level.


It is shown that after the application of DALF NC4 the average pollution declined to an acceptable low level. These numbers also show that the hygienic situation after treatment is on a constant low level. This situation will last for at least 3 years (HCP for 1 year). Therefore, the chances of a bacterial outbreak are considerably
smaller. Also the cleaning of the rooms will be easier and quicker, which is a welcome benefit in the current circumstances where the lack of personnel is felt seriously.

After treatment there were no polluted area’s (only 2 average) found in Room B (treated) where in Room A (ref) we found 7 polluted area’s (7 polluted and 1 average). During the testperiod the occupation of Room B was 100% where room A only had an occupation of 50%. In room A the remote control and the touchscreen
were cleaned and desinfected and not in use during the testperiod after the 9th of august which explaines the very good results in room A during this period.


In order to reach an acceptable level of hygiene, the use of DALF NC4 in the critical areas of the hospital is highly recommended. It will, without any doubt, secure optimal hygiene with less workload for the staff.

It will also secure the hygienic labor situation of the staff. It is likely that the usage of detergents end disinfectants will reduce dramatically.

General remark: all windows in the total ICU area should be closed. It makes no sense to have a filterer airconditioning system in the area when the windows and all doors are opened.
