Tumor metastasis is responsible for 1 in 4 deaths in the United States. Though it has been well-documented over past two decades that circulating tumor cells (CTCs) in blood can be used as a biomarker for metastatic cancer, there are enormous challenges in capturing and identifying CTCs with sufficient sensitivity and specificity. Because of the(More)
For several decades, cancer has been one of the most life-threatening diseases. For enhancing anticancer efficiency with minimum side effects, combination therapy is envisioned. The current manuscript reports for the first time the development of a methylene blue (MB) bound nanoplatform, which is capable of delivering targeted diagnostic and combined(More)
Multiple drug-resistance bacteria (MDRB) infection is one of the top three threats to human health according to the World Health Organization (WHO). Due to the large penetration depth and reduced photodamage, two-photon imaging is an highly promising technique for clinical MDRB diagnostics. Since most commercially available water-soluble organic dyes have(More)
Circulating tumor cells (CTCs) are extremely rare cells in blood containing billions of other cells. The selective capture and identification of rare cells with sufficient sensitivity is a real challenge. Driven by this need, this manuscript reports the development of a multifunctional biocompatible graphene oxide quantum dots (GOQDs) coated,(More)
Human cytomegalovirus (CMV) is a herpesvirus that causes major health problems in neonates as well as in immunocompromised individuals. At present, a vaccine is not available for CMV infection and the available antiviral drugs suffer from toxicity, poor efficacy and resistance. Here, we chemically conjugated a monoclonal antibody raised against CMV surface(More)
Choosing the three phenomenological models of the dynamical cosmological term Λ, viz., Λ ∼ (˙ a/a) 2 , Λ ∼ ¨ a/a and Λ ∼ ρ where a is the cosmic scale factor, it has been shown by the method of numerical analysis that the three models are equivalent for the flat Universe k = 0. The evolution plots for dynamical cosmological term Λ vs. time t and also the(More)
