Introduction: Dengue viruses cause either symptomatic infections or asymptomatic seroconversion. Symptomatic dengue has a wide clinical spectrum ranging from self-limiting infection to severe manifestations, mostly characterized by plasma leakage with or without hemorrhage. World Health Organization classification in 2009 classified dengue into dengue without warning signs, dengue with warning signs, and severe dengue.

Dengue is a viral disease present in many regions of the world. Aedes aegypti transmits it, and the most effective way to eliminate the mosquito is during the larval stage. Seaweeds possess metabolites with insecticidal properties, making them potential sources of new larvicides and viable alternatives to synthetic products used to control insect vectors of diseases.

In recent years, the increasing prevalence of viral infections such as dengue (DENV) and chikungunya (CHIKV) has emphasized the vital need for new diagnostic techniques that are not only quick and inexpensive but also suitable for point-of-care and home usage. Existing diagnostic procedures, while useful, sometimes have limits in terms of speed, mobility, and price, particularly in resource-constrained environments and during epidemics. To address these issues, this study proposes a novel technique that combines 3D printing technology with electrochemical biosensors to provide a highly sensitive, user-friendly, and customizable diagnostic platform.

Background: Aedes aegypti is the primary vector of dengue, chikungunya, and Zika viruses in Colombia. Various insecticides, including pyrethroid, organophosphate, and carbamate insecticides; growth regulators; and biological insecticides, such as Bacillus thuringiensis var. israelensis, have been used to control Ae.
