Abstract:
We developed a liquid crystal (LC) aptamer biosensor for the sensitive detection of amoxicillin (AMX). The AMX aptamer was immobilized onto the surface of a glass slide modified with a mixed self-assembled layer of dimethyloctadecyl [3-(trimethoxysilyl) propyl] ammonium chloride (DMOAP) and (3-aminopropyl) triethoxysilane (APTES). The long alkyl chains of DMOAP maintained the LC molecules in a homeotropic orientation and induced a dark optical appearance under a polarized light microscope (POM). In the presence of AMX, the specific binding of the aptamer and AMX molecules induced a conformatio

Abstract T Cell Engagers (TCEs) are a highly potent, cancer killing modality that redirect T cell cytotoxicity against tumors that express a selected tumor-associated antigen, or TAA, bypassing the requirements for T cell recognition of tumor specific MHC/peptides. In addition to their induction of direct cytotoxicity, their potency is amplified by cytokine driven actions downstream of T cell activation that enhance the anti-tumor immune response. Because of this two-fold mechanism of action, TCEs have demonstrated clinical activity in patients with “cold” tumors that are not responsive to oth
