Apparatus for blocking nucleic acids by means of photoactivating intercalating agents

An apparatus for blocking nucleic acids in a manner that covalently bonds the photoactivated intercalating agents with at least part of nucleic acids, comprising:

• a housing with outer perimeter walls demarcating an inner enclosure for housing a test or microcentrifuge tube containing at least one sample including nucleic acids and photosensitive intercalating agents mixed in liquid form, wherein at least one of said outer perimeter walls has at least one through-hole completely traversing a thickness of said outer perimeter wall and dimensioned for accommodating insertion there through at least in part the test or microcentrifuge tube containing the at least one sample including the nucleic acids and the photosensitive intercalating agents mixed in the liquid form;
• a removable test or microcentrifuge tube containing at least one sample including nucleic acids and photosensitive intercalating agents mixed in liquid form, wherein said test or microcentrifuge tube is inserted through said throughhole such that at least part of the test or microcentrifuge tube is arranged within said inner enclosure;
• and
• light emitting means for photoactivating said photosensitive intercalating agents in a manner that covalently bonds said photosensitive intercalating agents to at least part of said nucleic acids, said light emitting means including at least one light emitting diode (LED) arranged to emit light towards said at least one sample in the manner that photoactivates said intercalating agents to covalently bond said photosensitive intercalating agents to at least part of said nucleic acids, and said at least one LED being mounted inside said inner enclosure of said housing and arranged with respect to said at least one through hole and with respect to said at least one test or microcentrifuge tube such that said at least one LED emits light, in a determined direction, towards a portion of the at least one test or microcentrifuge tube, said portion including said sample and said intercalating agents mixed in the liquid form.
