Natural polymers have been widely studied as vehicles that have gained much interest in the encapsulation and delivery of drugs and bioactive molecules. In this study, we developed starch-modified alginate nanoparticles using a green facile technique for drug delivery application. The potential of the prepared nanoparticles for controlled drug delivery applications is demonstrated using theophylline and bovine serum albumin as model drugs. The nanoparticles possessed the encapsulation efficiency of 60 to 75%. The results of in vitro drug release studies showed the pH dependent characteristics of the prepared nanoparticles. In vitro cytotoxicity test revealed the biocompatibility of the developed nanoparticles against L929 fibroblast cell lines. The in vitro cellular uptake of nanoparticles was visualized in L929 fibroblast cells using fluorescent microscopy. The preliminary investigation suggests the developed nanoparticle is a promising candidate for drug delivery application.

Glioblastoma (GBM) is a malignant tumor with highly heterogeneous and invasive characteristics leading to a poor prognosis. The CD44 molecule, which is highly expressed in GBM, has emerged as a highly sought-after biological marker. Therapeutic strategies targeting the cell membrane protein CD44 have emerged, demonstrating novel therapeutic potential.

Purpose: Recent clinical advances with the approval of antibody-drug conjugates targeting Trop-2 such as sacituzumab-govitecan and datopotomab-deruxtecan have garnered tremendous interest for their therapeutic efficacy in numerous tumor types including breast and lung cancers. ImmunoPET can stratify tumor avidity, clarifying patient eligibility for ADC therapy as well as a diagnostic companion during therapy. Slow antibody circulation requires days to reach optimal imaging timepoints.

In many simple viruses and virus-like particles, the protein capsid self-assembles around a nucleic-acid genome. Although the assembly process has been studied in detail, relatively little is known about how the capsid disassembles, a potentially important step for infection (in viruses) or cargo delivery (in virus-like particles). We investigate capsid disassembly using a coarse-grained molecular dynamics model of a = 1 dodecahedral capsid and an RNA-like polymer.
