A highly sensitive facile plasmonic scheme for assessment of melamine in raw milk.

This work presents two novel devices with a microcontroller and two different light sensors, namely, Light Dependent Resistor (LDR) and Ambient Light Sensor (ALS), which can provide a quantitative output from the colorimetric variations of citrate capped borohydride reduced silver nanoparticles (AgNPs) and citrate capped gold nanoparticles (AuNPs) upon addition of melamine adulterated milk. The limit of detection (LOD) of the LDR setup with AgNPs and AuNPs was found to be 1.24 ppm and 1.

One-Pot Interference-Based Colorimetric Detection of Melamine in Raw Milk via Green Tea-Modified Silver Nanostructures.

Detection of melamine has proven to be a challenge, requiring the use of complex analytical techniques. This study introduces an innovative, straightforward one-pot technique for qualitative assessment of the milk adulterant melamine. Originally, silver nanoparticles (AgNPs) were synthesized by utilizing green tea extract, which acted as both a reducing and sensing element.

Highly sensitive biofunctionalized nanostructures for paper-based colorimetric sensing of hydrogen peroxide in raw milk.

Hydrogen Peroxide (HO) is a highly hazardous, toxic, and carcinogenic chemical compound utilised in various industries-based applications. Despite strict restriction, they are deliberately added to food items such as milk as preservatives to increase its shelf life. Herein, we have formulated a green rapid colorimetric nanosensor for detection of HO in milk using cotton leaves as both reducing and functionalizing agent for synthesis of silver nanoparticles (AgNPs).

Isolation, Detection and Analysis of Circulating Tumour Cells: A Nanotechnological Bioscope.

Cancer is one of the dreaded diseases to which a sizeable proportion of the population succumbs every year. Despite the tremendous growth of the health sector, spanning diagnostics to treatment, early diagnosis is still in its infancy. In this regard, circulating tumour cells (CTCs) have of late grabbed the attention of researchers in the detection of metastasis and there has been a huge surge in the surrounding research activities.
