Chambers finished second in the 100m trials in Birmingham
Dwain Chambers will run in the 100m and 200m at the World Championships in Berlin in August after being named in Great Britain's squad.
The 31-year-old joins Birmingham trials winner Simeon Williamson and Tyrone Edgar in the 100m.
Christine Ohuruogu will defend the 400m title she won in Osaka in 2007, despite struggling with a hamstring injury.
Lisa Dobriskey and Steph Twell join Charlene Thomas in the 1500m, while Paula Radcliffe goes in the marathon.
Radcliffe, along with UK 20km walk champion Johanna Jackson, had been pre-selected.
However, the marathon world record holder, who won the title four years ago, is a doubt for the Championships, which run from 15-23 August.
We are on a long term journey to 2012 but we can't wait three years for the medals and performances
UK Athletics chief Charles van Commenee
The 35-year-old, who missed the London Marathon after undergoing surgery to remove a bunion from her foot and could only walk a 10km charity race in May, is expected to make a decision next week.
UK Athletics chief Charles van Commenee said: "Paula is making good progress and has a 70-80% chance. It is her decision and I trust her judgement."
The Dutchman is hoping to match the five medals Britain won at the last World Championships in Osaka two years ago.
"It's an ambitious goal, but that's how we have to approach the Championship," he added.
Van Commenee was also keen to draw a line under the Chambers selection issue.
The former European 100m champion served a two-year ban for taking the designer steroid THG in 2003 and is included in the team despite not being available for Olympic selection.
Van Commenee stated: "We select on performance. The man has served his sentence, he's eligible to compete so if he runs fast enough he is selected.
"I've always been clear. He will be eligible for selection, but he can't run relays. There's no more to it."
Chambers will not be selected for the relays as van Commenee wants a potential Olympic relay team to have plenty of time to gel together.
The winner of each event at the Birmingham trials earlier this month was guaranteed selection for the World Championships, as long as they had achieved the 'A' qualifying standard, with two more places up for grabs.
Olympic 400m champion Ohuruogu won the trials, but she is facing a race to be at her peak for the defence of her world title in Germany.
The 25-year-old has struggled for form and fitness over the summer and the hamstring niggle forced her to withdraw from last weekend's London Grand Prix at Crystal Palace.
Nicola Sanders, who won silver behind Ohuruogu two years ago in Osaka, missed the trials through injury but showed a return to form with victory in south London last Friday.
The women's 1500m was one of the most intriguing selection issues.
Thomas, as a winner at the trials, was guaranteed her spot, while 19-year-old Twell, who tops the rankings, has won the European junior cross country title three times and achieved the standard twice in the qualifying period, has also been given the nod.
A strong trio is completed by Commonwealth champion Dobriskey. The 25-year-old was the leading Briton at Crystal Palace and finished fourth in the Olympic final in Beijing.
Hannah England, who was fourth at the Grand Prix, is the unlucky one to miss out, despite reaching the qualifying standard.
Van Commenee had some sympathy for England, saying: "It was a difficult decision and there was a good case for all of them.
"Dobriskey was convincing at Crystal Palace, plus she came fourth at the Olympic Games so the choice was between Twell and England.
"Twell has the fastest time this year and beat England at the trials so she had slightly more to bring to the table."
Jessica Ennis missed the Beijing Olympics through injury, but she leads Britain's hopes in the heptathlon following Kelly Sotherton's withdrawal through injury.
Ennis, 23, who finished fourth in Osaka two years ago, also goes in the 110m hurdles.
In the men's 400m, Martyn Rooney, who finished sixth in the Olympic final, joins Robert Tobin on the starting blocks.
On Friday, hurdler Will Sharman and 1500m runner James Brewer were added to the squad after narrowly missing out on the initial selection.
Also heading to the German capital are European Indoor 3,000m gold medallist Mo Farah, Olympic high jump and triple jump silver medallists Germaine Mason and Phillips Idowu and British pole vault record holder Kate Dennison.
Van Commenee added: "We are on a long-term journey to 2012 but we can't wait three years for the medals and performances. I want to see both in Berlin and then more next year and the year after until we get to London.
"This is our first staging post on our toughest ever journey."
