The development of highly efficient latent fingerprint (LFP) technology remains extremely vital for forensic and criminal investigations. In this contribution, a straightforward, rapid, cost-effective method has been established the quick well-preserved on multiple substrates, including plastic, glass, aluminum foil, metallic surfaces, so forth, without any additional treatment, based aggregation-induced enhanced emission-active conjugated polyelectrolyte (CPE)...
The increase in bacterial infection and antibiotic resistance has posed a severe threat to the human health. This warranted an imperative demand for development of new effective bactericidal material eradicate antibiotic-resistant pathogenic bacteria. In this work, we report wash-free imaging Staphylococcus aureus (Gram-positive) Escherichia coli (Gram-negative) bacteria using cationic conjugated...
Anionic conjugated polyelectrolyte PFT exhibits multiple activities of Cu 2+ sensing, PPi sensing (LOD 2.26 ppb) in physiological environment, monitoring ALP activity and intracellular imaging macrophages cancer cells.
Owing to unique photophysical and structural features conjugated polymers (CPs) have demonstrated high selectivity, specificity enhanced imaging ability are utilized for rapid latent fingerprint development using simple processing methods.
Flavins viz. riboflavin (RF, vitamin B2), flavin mononucleotide (FMN) and adenine dinucleotide (FAD) represent an important class of biomolecules ubiquitously found in living systems that are vital for numerous cellular activities inside the body. The fluorescence amplified detection these flavins at ppb levels is achieved first time using water soluble cationic conjugated polymer PMI under physiological conditions. substantial FRET, variable binding abilities with via Columbic interaction...
Considering the vital need to strengthen national security emanating from chemical threats, a low-cost, portable ultrasensitive electrical sensor for real-time monitoring of diethylchlorophosphate (DCP) (nerve gas mimic) has been developed. The device consists "simple be fabricated" two-terminal resistor and an electronic combinational circuit rapid onsite detection lethal nerve vapors with high degree accuracy in milliseconds. This is smart readout model that detects ultratrace DCP by...
A new highly conjugated polymer–bioconjugate poly[9,9-bis(6′-adenine) hexyl)fluorene-co-4,7-(2,1,3 benzothiadiazole)] (PFBT-A) is developed using the well-known Pd(PPh3)4-catalyzed Suzuki cross-coupling polymerization reaction with a simple purification method. PFBT-A showed excellent sensitivity toward iron containing metalloprotein and cancer biomarker ferritin detection limit as low 0.164 nM (i.e., 71.05 ng/mL), which much below level observed in blood serum of patients. Detailed...
