let g be a simple graph. the hosoya polynomial of g is ( , ) ,( , ) = { , } ( ) xd u v h g x  u v v gwhere d(u,v) denotes the distance between vertices u and v . the dendrimer nanostar is apart of a new group of macromolecules. in this paper we compute the hosoya polynomial foran infinite family of dendrimer nanostar. as a consequence we obtain the wiener index andthe hyper-wiener index of th...

objective: dendrimers are three-dimensional nanostructures that have numerous applications in medicine, including drug delivery and imaging. although anionic dendrimer polyethylene glycol–citrate has a high potential to increase solubility of water-insoluble drugs and drug delivery, its multi-step synthesis procedure is time consuming. in addition, toxic substances such as dichloromethane are u...

Atomistic molecular dynamics simulations have been carried out to reveal the characteristic features of ethylenediamine (EDA) cored protonated (corresponding to neutral pH) poly amido amine (PAMAM) dendrimers of generation 3 (G3) and 4 (G4) that are functionalized with single stranded DNAs (ssDNAs). The four ssDNA strands that are attached via alkythiolate [-S (CH2)6-] linker molecule to the fr...

We have designed a new type of a DNA dendrimer which has rigid branched structure. The branching molecule was prepared from 1,3,5-tribromobenzene. The dendrimer unit, in which three oligonucleotide-chains, two molecules of T15 and one molecule of A15, linked to the branching molecule, was synthesized by an automated DNA synthesizer. The properties of the dendrimer unit and dendrimer formation b...

Nanomedicine represents a very significant contribution in current cancer treatment; addition to surgical intervention, radiation and chemotherapeutic agents that unfortunately also kill healthy cells, inducing highly deleterious often life-threatening side effects the patient. Of numerous nanoparticles used against cancer, gold had been developed for therapeutic applications. Inter alia, large...

The antitumor effect of doxorubicin (DOX) conjugated to a biodegradable dendrimer was evaluated in mice bearing C-26 colon carcinomas. An asymmetric biodegradable polyester dendrimer containing 8-10 wt % DOX was prepared. The design of the dendrimer carrier optimized blood circulation time through size and molecular architecture, drug loading through multiple attachment sites, solubility throug...

BACKGROUND Polyamidoamine (PAMAM) and polypropylenimine (PPI) dendrimers are the commercially available and most widely used dendrimers in pharmaceutical sciences and biomedical engineering. In the present study, the loading and release behaviors of generation 3 PAMAM and generation 4 PPI dendrimers with the same amount of surface amine groups (32 per dendrimer) were compared using phenylbutazo...

C6-Fluorocarbon-dendrimer has been applied to the cotton knit fabric develop oil–water repellent, separation, acid-resistant, self-cleaning, UV-resistant, and antibacterial properties. The C6-Fluorocarbon (FC)-dendrimer-coated 100% single jersey knitted samples were prepared using “pad-dry-cure” method. 90 g/L 100 FC-dendrimer-treated fabrics showed excellent water repellency separation as well...
