The technology, originally developed in response to a need from the U.S. Defense Threat Reduction Agency (DTRA), uses a specially formulated liquid.<\/p>\n<p>This can be sprayed onto surfaces and, upon contact with the respective biological threats, visibly changes color, yielding immediate and easily interpretable results without complex equipment. \u201cOur work began with the characterization of biological threats, particularly with regard to biological warfare agents, but then expanded to sensor development with the aim of rapidly and reliably detecting these threats,\u201d said David Glasbrenner, lead molecular geneticist in the Chemical, Biological, Radiological, and Nuclear (CBRNE) Hazards and Energetics division at Battelle.<\/p>\n<h3><strong>Identification of Specific Pathogens by Color Change<\/strong><\/h3>\n<p>\u201cBy spraying the liquid onto a surface, users can visually detect a color change if a threat is present. It is precisely this simplicity that makes the method so powerful,\u201d said Glasbrenner. In contrast to other surface-analysis systems that merely indicate the presence of a general contamination, Battelle\u2019s technology can be tailored to identify specific biological pathogens. The detection function is based on an in-house formulation that binds to the respective target threats and subsequently produces a visual signal, enabling precise identification.<\/p>\n<div class=\"digimember_salesletter\">\n<style>.addtoany_share_save_container{display:none!important;} .g-8, .g-22, .g-21, .g-23{display:none!important;} .td-main-sidebar{display:none!important}body.td-animation-stack-type0 .post img { opacity: 1;}@media (max-width:475px){.paywall-column-1, .paywall-column-2{width:99%!important;}.paywall-order-1, .paywall-order-2,.paywall-order-3{width:99%!important;}}<\/style>\n<div class=\"digimember_login_info_pop\">\n<div class=\"paywall-column-1\" style=\"float: left; width: 50%; padding: 20px;\"><span style=\"font-weight: bold;\">Zum weiterlesen bitte mit Ihrem Soldat &amp; Technik Digital Zugang anmelden<\/span> oder einen <span style=\"font-weight: bold; color: #395021;\">Digital Zugang bestellen<\/span>.<br clear=\"all\"><\/p>\n<style type=\"text\/css\">\nform#login_2_form div.ncore_with_focus input[type=\"text\"],\nform#login_2_form div.ncore_with_focus input[type=\"password\"]\n{\n    border-color: #21759b;<\/p>\n<p>}<\/p>\n<p>form#login_2_form div.ncore_with_focus label,\nform#login_2_form div.ncore_with_focus label\n{\n    color: #21759b;<\/p>\n<p>}<\/p>\n<p>.button.button-primary.ncore_custom_button,\nform#login_2_form .button.button-primary {\n     background-color: #21759b;\n     color: #FFFFFF;<\/p>\n<p> }\n<\/style>\n<div class=\"ncore ncore_user_form_container digimember_login dm_signin_form_container ncore_with_wp_login ncore_without_fp_login\">\n<div id=\"login_2_form_error_message\" class=\"user_login_form_form_error_message\"><\/div>\n<form action=\"https:\/\/soldat-und-technik.de\/2026\/09\/sut-plus\/49853\/erkennung-biologische\/\" method=\"post\" id=\"login_2_form\" name=\"login_2_form\" class=\"ncore_user_form dm_signin_form ncore_form_narrow \">\n<div class=\"ncore ncore_user_form\">\n<div class=\"ncore_hidden\"><input type=\"hidden\" name=\"ncore_xss_password\" value=\"HmAMLiCUxFCAE6I1RE5ahJDTLL8ejL\"><\/div>\n<div class=\"ncore_form_row  ncore_input_text ncore_without_value\">\n<div class=\"ncore_form_label  \">\n        <label for=\"ncore_username0\">Username<\/label>\n    <\/div>\n<div class=\"ncore_form_input  \">\n         <input id=\"ncore_username0\" type=\"text\" name=\"ncore_username0\"><\/p><\/div>\n<\/div>\n<div class=\"ncore_form_row  ncore_input_password ncore_without_value\">\n<div class=\"ncore_form_label  \">\n        <label for=\"ncore_password0\">Password<\/label>\n    <\/div>\n<div class=\"ncore_form_input  \">\n         <input id=\"ncore_password0\" type=\"password\" name=\"ncore_password0\"><\/p><\/div>\n<\/div>\n<div class=\"ncore_form_row  ncore_input_checkbox ncore_without_value\">\n<div class=\"ncore_form_input  \">\n         <label><span class=\"ncore_checkbox\"><input type=\"checkbox\" id=\"ncore_remember0\" name=\"checkbox_ncore_remember0\" class=\"ncore_checkbox\" data-value-checked=\"1\" data-value-unchecked=\"0\"> <input type=\"hidden\" name=\"ncore_remember0\" value=\"0\" class=\"vis_sel_remember_830396495\"><\/span> Stay logged in<\/label><\/p>\n<div class=\"ncore_user_form footnote ncore_new_password_link\">Forgot password?<\/div>\n<\/p><\/div>\n<\/div>\n<\/div>\n<p><input type=\"hidden\" value=\"1\" name=\"ncore_ncore_is_posted_00\"><\/p>\n<div class=\"ncore ncore_user ncore_form_buttons\"><input type=\"submit\" onclick=\" var form = ncoreJQ( this ).closest( 'form' ); var container = form.parent(); var error_div =  container.find( '.user_login_form_form_error_message' ); var error_div_id = error_div.attr( 'id' ); var username = encodeURIComponent( form.find( 'input[name=ncore_username0]').val() ); var password = encodeURIComponent( form.find( 'input[name=ncore_password0]').val() ); var remember = form.find( 'input[name=ncore_remember0]').val() ?
