Abstract
Disclosed are real-time insect surveillance sensor devices and methods that use a colorimetric readout for detecting insect disease vectors (such as mosquitoes which can transmit pathogens such as DENV, CHIKV, and ZIKV). The method involves an attractive or feeding solution combined with detector conjugates. The conjugate can specifically detect proteins present in insect saliva and/or proteins specific to mosquito-borne pathogens.
Claims4
A method for detecting specific insects which may be located in an area which method comprises:
- providing in said area a device which comprises:
- (a) an internal payload reservoir comprising a payload solution, wherein the payload solution comprises:
- (i) an insect attractant or insect food source, wherein the insect attractant or insect food source is sugar water;
- and
- (ii) a detector conjugate comprising a gold nanoparticle conjugated to a specific detector molecule that binds specifically to a protein present in the saliva of the specific insect, wherein the specific detector molecule is an aptamer;
- (b) an internal transfer wick;
- (c) a secondary reservoir;
- and
- (d) an outer releasing wick;
- allowing said specific insects to alight on or feed on said device under conditions suitable to allow the binding of said protein to said detector conjugate to form an agglomerated detector conjugate;
- and
- visualizing or quantitating the binding of said protein to said detector conjugate to form an agglomerated detector conjugate to determine the presence of the protein.
A method for detecting an insect infected with a pathogen which may be located in an area, the method comprising:
- providing in said area a device which comprises:
- (a) an internal payload reservoir comprising a payload solution, wherein the payload solution comprises:
- (i) an insect attractant or insect food source, wherein the insect attractant or insect food source is sugar water;
- and
- (ii) a detector conjugate comprising a gold nanoparticle conjugated to a specific detector molecule that binds specifically to a pathogen protein present in the saliva of an insect infected by the pathogen, wherein the specific detector molecule is an aptamer;
- (b) an internal transfer wick;
- (c) a secondary reservoir;
- and
- (d) an outer releasing wick;
- allowing said insects to alight on or feed on said device under conditions suitable to allow the binding of said pathogen protein to said detector conjugate to form an agglomerated detector conjugate;
- and
- visualizing or quantitating the binding of said pathogen protein to said detector conjugate to form an agglomerated detector conjugate to determine the presence of the pathogen protein.
